I just installed some 00 ITR cams, a skunk 2 Intake manifold and 70mm Throttle Body on my B20vtec turbo setup. The car was tuned before I had this stuff. I had been driving the car around with the skunk 2 stuff for about a month now (weekends only). I didnt have a problem at all until I installed the cams then the car started to spike and hit boost cut. Im currently on 13-14psi tuned but it wants to hit about 16psi(boost cut). Car seems a bit sluggish now in higher gears. Here is a pic of my #4 cylinder plug which looks the worst, the other 3 look pretty normal. This is the first time actually taking the plugs out for about 2-3 months.




These are also 3 step colder plugs. My tuner also tuned pretty conservative. Should I be ok if I just get it retuned.

 

retune since you changed the cam profiles.

 

put a fresh set of plugs in and retake your pics.....

 

Why did you post this twice? Either you think the folks in the F/I forum are dumb, or the folks in here, and you don't trust either of them. keep it to one thread, you got all the answers you need in the F/I forum already
