The calibration is written for your car

Your file is written around the parts already bolted to your car, not pulled off a shelf. You flash it yourself with your own SCT, HPTuners, Holley EFI or ACES EFI device, then drive it and send a datalog back. Bill reads the log and revises until it is right.

Every car is different, so this is one result and not a promise. What it shows is that the numbers here come off a dyno in Monroeville, NJ, not off a spreadsheet.

the rollers

Bring the car to the shop in Monroeville, NJ and we tune it under load on the rollers. Pull after pull, we watch the data and adjust until the calibration holds. A full session runs $899.99, and the dyno rents at $200.00 an hour if you run your own numbers.
