[QUOTE="P49Y-CY, post: 16289286, member: 10216"] still been working on this here and there. still don't have it solved, but definitely getting closer... even if only through the process of elimination! lol at this point i have swapped out just about every part that i could get to without dropping the fuel tank: maf sensor, iat sensor, air intake filter, throttle body/elbow, injectors, fuel rail pressure sensor, fuel pump relay module, pcv valve, egr valve, etc. neither my xcal2 or xcal3 seem to be cooperating with either livelink program, so i still havn't been able to do any datalogging. maybe they are just out of date. but to update the xcal3 device from the sct website software i would need to load my stock tune on my coupe and i don't really feel like doing that. so at this point, i am going to try swapping out the fuel pumps. i checked the prices and they are pretty expensive, so i don't want to buy them in case it is still not the issue. but unfortunately i will need to drop both gas tanks to do that. i have never dropped the gas tank before, but i will say that overall this has been a good learning experience for me so far!
