Have HP Tuners but don’t know where to start? Let us build you a file. Your gains will depend on the modifications that you have done to your vehicle, but generally we are able to pick up about 10-14hp (I4 & I5) and 15-20hp (V8), along with better gas mileage and driveability. After placing your order, please click on “Ordersheet” on the top menu and fill out a tuning ordersheet for your vehicle. Then, email a copy of your STOCK file to firstname.lastname@example.org for tuning! NOTE: The cost of the email tune includes three free revisions (based off of datalogs you submit). Every file revision/review after the intial three is $5/file. Future reflashes are $50 (if you add/delete modifications).
