Just installed heads and cam and my ltft's are a bit off from each other... My bank 1 is around -1 to -2 and my ltft bank 2 is around -4 to -7... Could this be an o2 sensor or an exhaust leak?

thanks

Ill try and get some logs and more info... thanks

Try and look at more than just the LTFT's. Pick a couple VE cells in a couple different fuel trim cells. What's the difference between the (AVG_LTFT+AVG_STFT) for bank 1 and bank 2 in those cells? What I'm getting at is, the LTFT for bank 1 might be -3%. But the STFT's might be averaging -1% effectively giving your fueling a -4% correction. If the other bank has a -6% LTFT and avg STFT's are +1%, then you have a -5% correction....or a difference of 1%. 1% is not that much, but it looks like more when you see -3% and -6%.
