· IN-PERSON ONLY Franklinville, NJ Area ·
Perfect idle. Clean cold starts. Hard pulls and ready to rip
If you’re running Holley EFI on a street car, your goal is simple: a car that starts every time, idles rock solid in traffic, drives like OEM, and absolutely rips when you put your foot down. Not a science project. Not “it’s a race car, live with it.”
The Streetcar Holley EFI Pro Tune is a full street / road tune designed to give you exactly that:
-
Stable idle in gear and at lights
-
Clean cold starts without feathering the throttle
-
Smooth drivability around town and on the highway
-
Full-throttle calibration so the car pulls hard and safely
All specifically for a street-legal, roadworthy vehicle.
What’s Included

In-person street / road calibration for Holley EFI systems, built for daily-driven and weekend street cars:

-
Cold-start, idle, and drivability tuning so it behaves in real traffic, not just on a dyno
-
WOT calibration for safe, repeatable pulls
-
Drivability Guarantee
-
1 Free Seasonal Revision within 12 months (no new hardware mods) to keep it happy in summer/winter

Driveability Guarantee (Our “It Just Works” Promise)
If your car is mechanically healthy and street legal, we guarantee:
Stable idle, clean cold starts, and smooth pulls within 30 days of your tune, or we keep working at no additional labor charge until it’s right, or we refund the labor.
Free Seasonal Revision
Your Pro-Tune includes one free seasonal revision within 12 months, as long as you haven’t changed any hardware.
When the weather swings (hot to cold or cold to hot) and the car feels a little different, you simply book a Seasonal Revision through your portal. If you’ve changed parts (cam, turbo, etc.), that’s a Retune, not a seasonal revision. This is a built-in follow-up so your car stays dialed all year without a surprise bill.
If you don’t need to use the Seasonal Revision in that window, we’ll credit its value toward your next tune or retune, stacking more upside for you. ($300 VALUE)
Why This Is a Bargain
Most Holley EFI tunes run $600–$900 for a basic dyno session with no street drivability guarantee, no seasonal revision, and no structured support. You’re paying “per pull” and hoping it drives right afterward.
For $999, you get:
-
A street-first calibration built in real road conditions
-
A Free 12‑month seasonal revision baked in
-
A real driveability guarantee instead of “all sales final”
-
Transparent pricing, no surprise labor charges.
Plus, you can:
-
Pay in full: $999
-
Split it up: We accept 0% financing options like Affirm
You never have to piecemeal dyno time and or deal with mystery pricing again.
How It Works
-
Book your slot online
-
Choose Full Tune, add any options, pick a time.
-
Confirm you’re within our Franklinville, NJ service radius or can get the car to our shop for your appointment. Make sure the car is street legal and roadworthy (brakes, tires, etc.).
-
Prep & safety check
-
You’ll get a simple pre-tune checklist and a vehicle / liability form to complete at least 24 hours before your appointment.
-
On arrival, we re-check safety so road tuning is safe for both of us and we can make the most out of the time.
-
In-person street tune
-
We road-calibrate your Holley EFI for cold start, idle, cruise, and WOT.
-
You leave with a backed-up tune file, access to your customer portal, and clear instructions for using your post-tune support / seasonal revision if you purchased it.
This is not a remote-only product and not a race-only dyno hit. It’s a street/road Holley EFI Pro Tune for legal, roadworthy cars that you actually want to drive.
If you want your Holley car to behave like it’s factory engineered and still hit like a freight train when you stomp it, this is the last tune you’ll need.
Drivability Guarantee
If we don’t deliver stable idle, clean cold start, and smooth WOT pulls (assuming no mechanical faults), we keep tuning at no extra cost until it’s right or we refund the labor fee. Simple.
Mobile Service
If your build isn’t road-ready, we’ll come to you. Whether it’s in your garage or on your trailer, we’ll get it running where it sits. No extra cost, no excuses.
Free seasonal revision
You want a strong cold start in winter, and smooth idle in summer. If temperature swings cause drivability issues within 12 months, we’ll retune it at no extra cost.

Here we answer the most common questions we get.
If you can't find the answer to your question, please contact us
What exactly is the Pro-Tune?
What exactly is the Pro-Tune?
It’s an in-person, street / road tune for Holley EFI street cars. We dial in cold start, idle, drivability, and WOT in real-world conditions (just like the OEM's do) so your car starts, idles, and drives like it should on actual roads, not just on a dyno.
Do I need to come to you, or do you come to me?
Do I need to come to you, or do you come to me?
Both are available within our service radius. You can either:
- Drive / tow the car to us in Franklinville, NJ, or
- Choose mobile tuning if you’re within our local road-tuning radius (no extra fee; must be safe to road test near you).
You’ll confirm which option fits you in the booking form.
Does my car need to be street legal and roadworthy?
Does my car need to be street legal and roadworthy?
Yes. This is a street/road tune, not a “starts in the bay, never leaves the lot” tune. You must confirm:
- Brakes, tires, steering, and suspension are safe
- Lights work and the car is safe to drive on public roads
If the car isn’t truly roadworthy, we’ll still do what we can, but there are no discounts if your prep isn’t done.
How long does the tune take?
How long does the tune take?
Plan on a half day for a standard Pro Tune. Some cars are faster, some need more road time. Your appointment window is blocked so we’re not rushing your calibration. You're paying for the outcome so we dont stop until the car is right.
What if my car has mechanical issues during tuning?
What if my car has mechanical issues during tuning?
Tuning will not fix mechanical problems. If we find issues (fuel pressure, vacuum leaks, ignition faults, etc.), we’ll pause, show you what’s wrong, and you can either:
- Fix it on the spot if it’s simple, or
- Rebook after repairs
Mechanical faults void the guarantee until they’re resolved, because no tune can overcome bad hardware.
How does the Driveability Guarantee work?
How does the Driveability Guarantee work?
If your car is mechanically sound and street legal, we guarantee:
- Stable idle
- Clean cold starts
- Smooth pulls
If we don’t hit that within 30 days of your tune, we keep working at no extra labor charge until it’s right, or we refund the labor fee.
How does the Free Seasonal Revision work?
How does the Free Seasonal Revision work?
Your Full Holley EFI Pro Tune includes one free seasonal revision within 12 months, as long as you haven’t changed any hardware. When the weather swings (hot to cold or cold to hot) and the car feels a little different, you simply book a Seasonal Revision through your portal.
If you’ve changed parts (cam, turbo, etc.), that’s a Retune, not a seasonal revision. This is a built-in follow-up so your car stays dialed all year without a surprise bill.
What if I don’t end up using the Seasonal Revision?
What if I don’t end up using the Seasonal Revision?
If your car is dialed and you never need the Seasonal Revision in the window, we’ll credit the value of the revision toward your next tune / retune, acting like a credit-based guarantee. ($300 Value)
You either get extra support now or extra value later.
What platforms do you support?
What platforms do you support?
We specialize in Holley EFI street applications (Terminator X, HP, Dominator, Sniper EFI conversions, etc.).
If you’re unsure, you can contact us first or list your exact setup on the intake form and we’ll confirm before your appointment.
Do you offer dyno testing too?
Do you offer dyno testing too?
Dyno testing is an option for existing Pro-Tune customers. We work with our dyno partner and their rate/schedule. The dyno is used for validation and refinement, not guesswork pulls.
Can you tune me remotely?
Can you tune me remotely?
Yes, remote support is an option for qualified cars and customers, typically after an in-person Pro-Tune or for minor revisions. It’s not a replacement for the in-person Pro-Tune if you’re within our radius.
Can I reschedule if something comes up?
Can I reschedule if something comes up?
Yes. You can reschedule up to 48 hours in advance without penalty. Inside 48 hours, your deposit is kept and the rest is refunded or applied per policy.
We are humans here so please reach out if something is seriously going on.
What do I need to do before my appointment?
What do I need to do before my appointment?
After booking you’ll:
- Complete a vehicle info form and liability form (at least 24 hours before).
- Follow a simple pre-tune checklist (brakes, tires, fluid leaks, etc.).
- Show up with enough fuel and a reasonably clean, ready-to-drive car.
If the forms are not completed, your appointment may be cancelled and refunded automatically per the stated rules, because we can’t safely or efficiently tune without that info.
