I got one more question, I just checked out TAP cuz i was looking for springs, but I looked at their chips and they claimed 110 HP!!! Damn that seems like an awful lot from a chip and a wastegate spring. They have to be running like 27 PSI to get these numbers right? Has anyone used the TAP stage 4 chip set. Because 110 hp for $900 bucks seems like one hell of a deal because i run premium anyway and my cars stock.

However, I am running TAP stage II, and it's fine. I like it. I'll probably switch to Mihnea once I do a bit of serious modding.

Ned Richie, Mihnea, MTM, etc.

Ned is at Intended Acceleration.com
Mihnea can be found on this board
MTM is through Joe Hoppen Motorsport.

None of then require the wastegate spring.
