I just finished my rebuild on on my sr. I changed my set up a little bit and have lost all my mid range power. I run a gt2876r , deatschwerks 740's, nismo rom tune, z32 maf, crower stage 3 cams 272. hks springs , and a knock off greddy intake mani. their is more but I figure thats all you will need to answer my question. my old set up was almost the same as it is now. only differences are used to run nismo 740's , stock intake mani , and hks 272 stap 2 cams. I have also added a safc2 now to tune for the slight difference in the injectors. the car has very little power below 6k rpms. I can watch my boost gauge and I have about 10 psi at 3k but no power. the rpms slowly climb till around 6k and then the thing screams. in third gear traction loss at around 65mph. but the thing is a dog till those very high rpms. are my cams screwing me? the old setup would pull like nothing else through the entire rpm range. and my air fuel ratio i know is to lean but around 12.5 when it is dogging through the rpms. timing is set to stock 15 and plug gap is .029. pleas help explain my turd sr.
