Services & Pricing

At Hill Boys Tuning, every calibration is customized to your build. Whether you need a simple startup tune to get your project running or a full forced-induction calibration, my goal is to provide custom solutions to so you enjoy driving your car. 

​

​While I  tune late-model vehicles often, I feel more connected to helping those who’ve swapped modern powertrains or EFI systems into older cars. It’s a unique niche, and one I’m excited to help with.

Base File - Start up Tune

Step 1:

  • Fill out the intake form with all your build details.

 

Step 2:

  • If you’re using an OEM stuff, you'll send me your ECU so I can bench flash it.

  • If you’re running Holley or another aftermarket ECU, I’ll create a start-up file and send it to you with instruction on how to load it.

 

Step 3:

  • The cost of your start-up file will be credited toward a full tune whenever you’re ready.

 

Optional:

  • If you’re local to the greater St. Louis area, I may be able to come out and load the file for you depending on my availability.

Full Calibration

** Remote Tuning Available on Aftermarket, Stand Alone ECUs**

​

Step 1:

  • Fill out the intake form if you haven’t already.

 

Step 2:

  • Once it’s submitted, I'll reach out so we can get on the same page with what you're wanting.  Then, I’ll coordinate with you to set a drop-off date.

 

Step 3:

  • Calibration work begins. Depending on the complexity of your build, the turnaround can be as quick as same-day, but some projects may take a few days. If kept overnight, your car will be garaged.

  • During this process I’ll:

    • Dial in drivability.

    • Refine idle quality (stable cold starts, hot starts, and coast-down to idle).

    • WOT tuning for safe power delivery, proper fueling, and timing under load.

 

Step 4:

  • Once tuning is complete, I’ll coordinate with you for pickup and walk you through the results.

At Track or Dyno

Have a race coming up or want to squeeze everything out of your setup on the dyno? I’m happy to come along and focus on dialing in power under load—WOT pulls, boost targets, fueling, and timing—to safely get you the most horsepower and the lowest ET possible.
