I have some choices for what Chip to stick in the ECU. It currently has a Superchip and the car is running fine, smooth and progressive.
However I'm not sure how much extra power the Superchip gives? The alternative is to buy a Phase chip. Phase 1 seems an obvious choice but is there any difference between Phase 1 and 2? I know the Phase 2 kit comes with an intercooler but we will fit a large custom intercooler anyway. Is the only difference between 1 & 2 the large intercooler? Or do the chips run different boost pressures and if so, what are they?
