600whp-Prelude Posted October 7, 2008 Share Posted October 7, 2008 I am planning on installing an STI UpPipe and a Megan catless DP with an e-cutout dumping about where it meets the catback, and those will be my only mods besides a trans cooler. Is a tune absolutley needed, or can I get away with it for a while until I can get a COBB AP? Also, what are the differences between the version I and II ap's? Thanks.

600whp-Prelude Posted October 7, 2008 Author Share Posted October 7, 2008 I just figured I would start with the exhaust, then save up for a front mount, VF39 and the COBB AP, and do that all at once and get it tuned. Link to comment Share on other sites More sharing options...
Dark-V Posted October 7, 2008 Share Posted October 7, 2008 I do believe people recommend a tune with stage 2 due to risks of boost spikes. Correct me if I'm wrong though! Link to comment Share on other sites More sharing options...
