#213321 so i got my si runnin and put my z6 with the super charger in it, well when you drive it runs perfect when you get on it, and if you drive it normal it runs good from idle to 3k then stumbles till 4k and runs good after that.

there are no cels, ohh and if im just cruisin down the sreets after like a min of a constant rpm it will start to sputter and i have to push the clutch and give it a rev and that seems to clean it out. anyone got any ideas???

#213327 get her tuned!

and also try a basic tuneup with cap, rotor, wires, and plugs. might clear up your little issue

#213331 yea i just did a basic tune up on it before the s/c

as for a tune thats hard because there is no where close to me that tunes, also what do i need to do to my p28 for it be able to run chrome, i mean if i find a tuner then can he install chrome and all that ?

i was running the same plugs in my 4dr with a head swap header and intake, and it ran like a champ.. best running car i have ever had..



back to OP. any other mods to your motor or set up like intake header cams?? i will see if i can find you a really cold plug :thumb:

#213540 so you just slapped the blower on it and are running it without having it tuned? :o did you at least fallow the instructions from Jackson Racing on how to pull the timing with your factory ecu?

if not you are taking a major gamble in my book...
