I've actually been having problems with the car lately. Car ran fine when it came off the dyno, but soon there after it started having problems with a rough idle, and going extremely rich around 4.5krpms on and off boost. Fuel pressure on and off boost is great. Map sensor, tps, air temp, water temp etc all check out. As with injectors and O rings. Put brand new plugs in it with no change. I'm picking up a ignitor, coil, and cas censor from a buddy tonight to see if thats what my problem is. I'm hoping so, because I'm starting to get realy frustrated with it. I've been even thinking about selling it and getting a bike. If anyone has any advice, let me know. CJ

Yeah, that is not what I want to hear. Then again, my Stage I only has about 5k on it, and I'm only running 15 psi...should last a bit, I hope.

Yeah, when and if this turbo lets go.....I think I'll go with a GT42. I'll probably go with a T-66 or something along those lines.

I have'nt taken it to the track yet. I'll trying to sort out all my other problems with the major hesitations and stuff. Then I'll take it down to the track. I'm not expecting much, as it just blows the tires off in 1st and 2nd gear. I have'nt tested 3rd gear yet. I won't be interested in times, but what the car traps. Last year, with non-seq twins, stock cat back, and untuned it turned 117mph. I'm hoping for 125+ this year, if I don't get kicked out for not running a cage. I'll let you know when I do get a chance though. CJ

Sweet numbers CJ. That thing must go crazy fast now. Good luck with the rest of your tuning.
