So I recently installed my ported upper and lower mani and bored throttle bodies. Went to have a tune yesterday and my tuner said my AFR is all over the place. Bank one is reading 1.5 to 2.0 richer than bank 2. When he tries to adjust the fuel and go up both go down. At idle the AFR is the same. Also my idle is right at 900 rpm. Any suggestions

 

Did you do the idle relearn?

 

Yep that was the first thing I did
