STFT differences

weebs25

Hey everyone. Just got my gtm stage 2 sc on..trying to get stuff nailed down here for tuning with Eugene/ecutek. Had an issue before with the smaller injectors /something just not working properly so I bought 1300s..that issue was gone - but now I have my stft readings roughly a +15 difference on one then the other..idle is low occasionally dropping and hardly running. I have seen a few posts about this way back but no posts where they ended up. I did just have new gaskets/ FI test pipes cleaned up and sanded down back to new..not assuming I have a leak on the front of them. Going to get the car up and check today but just thought I would see if anyone else has any suggestions or has ran into this? It’s quite a difference on bank 1 /bank 2
