I let it warm up for about 5 minutes and it seemed fine...drove it around and it seemed ok...as soon as i boost and let off it starts acting up. When i try to hit the gas the revs drop down to around 200 rpms for a few seconds then itll jump up to where its supposed to be. Im using 3 check valves and my friend said that he could hear them while it was idling. I think that they could be the problem somehow. I also have 4 vaccum lines t'ed from the fpr...im sure that isnt helping but i couldnt find t's that would work for that. What do you guys think?

PS- Its a 90 crx dx w/turbod LS, custom t3/t4 running 7 psi, blah blah blah...

someone correct me if I am wrong but you shouldn't hear the check valves at idle. Under vaccum they are closed and at boost they open up to let out pressure. Either the check valves are bad or you have them hooked up backwards. With 7psi you may not throw a cel light if you took the check valves off. I ran 9 on my car for a year and never got a cel.

I believe your right.

 

check valves or any form of map sensor manipulation
