Trying my best to figure this issue out! I installed a set of FIC 525cc injectors along with holly high flow fuel rails. i thought i was able to dial the fuel in until i had a set of American racing long tube headers installed with high flow cats. there is a noticeable exhaust leak (the shop that installed it was ass) would that be causing my car to run rich then lean through the drive? i just cant seem to get the fueling down! also on downshifts it sounds like its choking itself out. i am lost and can use some help. attached is my recent tune Engine and trans and my most recent data log!

i would get the exhaust leak fixed , once you do reset the fuel trims and i bet everything will fall into place as far as your fueling when it follows from 1 bank to the other.
