CalibratedPower Vortec Tunes w/o Device | CPGMTUNES | 1998+ Chevy/GMC (Gas)

We use EFILive, a high powered calibration software along with our Mustang dyno to develop proven tunes to get the most out of your Vortec engine and transmission. This software gives us un-paralleled access to your engine and trans controller so that we can build highly refined tunes that maximize performance, efficiency, and most importantly - Driving Experience. The big name H-tech and S-chips of the world add a few degrees of timing and call it a day. NOT HERE. They don't even have access to tune the late model transmission control modules. At Duramaxtuner.com we start with the appropriate stock files for your truck and make hundreds of adjustments with your trucks intended use in mind.

Your tunes will be delivered to you on our EFILive based SPADE hardware platform (not included). This unit not only serves as a flash tool, but also as diagnostic scan tool for every GM in your driveway. If down the road you decide you want to tune another one of those vehicles in your driveway, you can do so using this one piece of hardware. Simply purchase one of our 'tuning only' products and an additional license.
