ok well im not to sure about all the tuning and stuff cause its a budy of mine that is doin it... he has his laptop and some atf comps hooked up and we go drivin round so he tunes it on the fly then goes burns me a chip with the new map on it. but im runnin a b20 with 450cc injecters out of a dsm, and they have bin all modded and we got the resister box in, uhhh got a garrett t28 turbo with the wastegate set at 8 lbs. all i know about the tuning is he uses a program called chrome. but he knows wat hes doin he has turboed lots of cars and this is the first time hes ever seen this and says it shouldnt be doing it and theres no reason for it but its just doing it..
