You got something going on then, because that's not normal.

Like I said, I think its the bypass spring, it has always done that since I first got the blower. Its fine though, if its not making what I want I just let off a little bit then stab it.

From what I could see timing fell from 24 to 12.

The # 1 injector plug had to be the problem, the afr was fine and it pulled really good this am...almost too good..lol. Under full boost the afr was low 11s, cruise was about 15s and idles off I guess with the super cold weather 14-16.

I have a new weather pack end and pins to swap on later today. The one I thought had the oring pushing out the connector.

No clue but it cant be normal. Mine feels instant and I mean instant. As soon as I blip the throttle while driving it jumps immediately and mine cant be anything special.

Yeah I don't think it's right either....damn sure doesn't feel right. I was thinking the bypass might have something to do with it. I'm gonna get a boost gauge and a wideband and check it out. Looking for more boost and cubes, Kinda hooked on the torque now. Anybody have any idea what it could be?
