Grand Prix GTP Tuning - Contents Under Pressure

Serious intake and exhaust mods are implemented on our GTP (X-P) to push power production well past 405With our latest round of upgrades finally complete, the time came to try out our newfound power. While driving around town the Pontiac was still docile, maybe even enough to make it a daily driver. This type of situation is where I advise having a scan tool of some sort to make sure everything is in check. I recommend Autotap from B&B Electronics because it allows you to check out your engine's management system as well as transmission controls and other parameters using your laptop computer and a supplied cable. I would not attempt half of the projects we have on any OBD-II controlled vehicle without some sort of scan tool to make sure everything is in check. After running through some basic tuning parameters at part throttle, it was time for a wide-open blast, and boy what a rush it was. At the 40-mph downshift to first made possible by the DHP PCM, the GTP absolutely incinerated the wide BFGoodrich tires and continued the process clear into second gear.
