I have an 03 vert, 20k miles maintained well and clean. The 2.9 whipple arrived at my house Monday and I am getting the car tuned friday. I have 63lb injectors, GTpumps, stage 2 driver, pprv delete kit, LFP heat exchanger and tank, C&L intake, 95mm mass air housing and Diablo Sport Piggy Back, LFP single blade T-Body, off road X, 2.5" cat back, 2 step colder plugs etc etc...I will be using the 3.5" whipple pulley that came on the blower. Whipple talked me into going with the 2.9 over 2.3.(I actually saved money, long story). They told me that with the 3.5" pulley and my stock lower I should be around 18psi. I will be running 93 octane fuel and my tuner will be using the SCT programming as he did on my other cars. I dont post alot, usually just read. I will be back on this forum Friday after my tune. I will let you guys know what happened.
Start a new thread when you come back so yours doesn't get cluttered up in this crazy thread.
Congrats on the whipple and good luck with the tune
