Have HP Tuners but don’t know where to start? Let us build you a file with our GMT355 Remote Tune. 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 drivability. After placing your order, please click on Order Sheet on the top menu and fill out a tuning order sheet 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 or review after the initial three is $5/file. Future reflashes are $65 (if you add/delete modifications).

We use our 20+ years of in person and GMT355 Remote Tune experience to make the best of your build. HP tuners allows us to review your datalogs, making sure we get the best power and driveability with our tuning. We support almost every LSx and LTx, and also GMT355 four and five cylinder engines. Wideband feedback and HP Tuners Pro may be required for some set ups. We also sell HP tuners here – link. If you aren’t able to bring your vehicle to us in person, this is the next best thing. We start by taking your stock file and building a tune with all of your order sheet taken into consideration. After receiving that file, you flash it, and then use our channels list to datalog with. Email us your datalog, and we’ll send a new revision until we are happy with how it looks. Simple as that! We use the same processes that we do when tuning a car in person.
