On my '94 TT, I have currently JWT SinglePop, UD Pulley, JWT ECU & Boost Jets, CZP TP's, & DeluboZ Catbacks. That is (according to SGP's Stage Chart) a Stage IV car, except I don't have gutted Pre-Cats (still have my stock pre-cats). I want DP's, but am trying to hold off until I have to drop the tranny for something else, or until Greg Dupree comes out with his full 3" exhaust (which I'd buy asap). The next stage is supposed to be EVC, followed by JWT NOS.1) Is the EVC a good idea before considering NOS? 2) Will having my stock pre-cats present a problem if I add NOS? 3) I've seen mixed reports here about upgrading injectors prior to NOS. Is this necessary? GPA
