Hi, i have a 96 GSR with an 01 B18C1 with a t3/t4 turbo and i was wondering if anyone had any ideas of why i can roll into third gear vtec and hold boost but if i go from boosting in second gear and shift into third i lose boost as soon as vtec hits (5600rpm). i have NGK iridium plugs and im set at 9lbs of boost. seems much like boost cut but im pretty sure that isnt it. i was thinking it might be the plug gap cause they are set at factory and im not sure if anyone has played with different gaps with this problem before, maybe a different kind of plug? maybe a colder plug?.. any ideas would help me a lot.. this problem is pretty embarresing. Thanks

 

i just went through this with my car. what type of air filter are you running?

 

plug gap should be around .030

 

hmm....did you check all your couplers and piping?? You sure the blow off valve isnt leaking?

 

I would ditch those iridium plugs and get a set of NGK BKR7E plugs. Gap them to .030".
