What does a tune do to a car or truck?
The majority of LSx & LTx (Late Model GM) vehicles can benefit from tuning, even in stock form. Using HP Tuners software, we modify many tables in the engine and transmission control modules that come together to make a big difference in power and responsiveness. Typically we modify things such as fueling (MAF and/or VE, VVE), timing, power enrichment, speed/rev limiters, transient modifiers, transmission upshifts & downshifts, torque management, and much more.
Even though these vehicles are built at factories, they can end up slightly different. Customers live in different places, use different gas, add some or no modifications. Some vehicles are just better performers than others from the factory. Tuning helps level this playing field. We pick up where GM left off to help you get the most out of your build, or stock car. LSx & LTx mail order tuning can be a great bang for the buck. We have more info on mail order tuning here – link.
What is mail order tuning?
With mail order tuning, you send in your module(s) to us, we tune them based on your order sheet, and ship them back. For certain vehicles, we offer core or loaner programs, where we send a module to you (available programs). Some vehicles have an ECM that controls both engine and transmission, and some will have a separate transmission control module that only controls transmission functions. Most of our listings mention this but if you are unsure, contact us first.
What is dyno tuning?
Dyno tuning is also performance tuning, but with the use of a chassis dyno. A chassis dyno is like a treadmill for a car. It allows us to do repeated testing at wide open throttle in a safe, controlled environment.
With more than twenty years of fuel injection tuning experience, we are able to offer both our expertise and our DynoJet 224xLC chassis dyno for fine tuning your vehicle. For our in-house builds, we include complimentary baseline pulls on the dyno (2WD only) to give us a benchmark to compare our final results with. This also ensures us that the vehicle is performing as it should before we modify dive into your build, saving time and heartache. For vehicles unsuitable for the dyno, we offer street tuning as well. This includes everything we normally do on the dyno, without getting on the dyno itself.
