I installed my 6 pos chip with php tunes on it tonight. Can not believe the power increase. One question, is the chip supposed to increase boost? Truck is so much more responsive and nicer to drive but the boost still seems to be around the same. Not complaining just curious. Truck is a 96 with 3in dp, 4in exhaust no muffler of cat, 6637 intake, and egt, boost and trans temp gauges.
