Below is a few of the other great features you can expect from your Dizzy Tuning Flash Tune: 91 and 93 Octane Compatible Dyno Proven Power/Torque Increase Eliminates Surging for Smoother Part Throttle Response Increased/More Consistent Boost Levels Increased Engine Idle Speed to Reduce NVH Caused By Aftermarket Motor Mounts Selectable Options (shown below) During testing, it was determined that the majority of the more popular engine modifications (intake, downpipe, catback exhaust) did not have a large effect on engine horsepower. In fact, it appears that the vehicles with little (or even no) engine modifications, were making the most power. However, the addition of an aftermarket intercooler did greatly help to reduce engine/cylinder temps, and almost completely eliminated knock (where knock was previously present). As a result, we have established the following: The Stage 1 Flash Tune is for vehicles running the factory intercooler. The Stage 2 Flash Tune is for vehicles running an upgraded intercooler.
