I have a 96 M52b28 (Cast Iron Block). The engine has been fully rebuilt and it is now 11:1 for boost with good e85. Im running into an issue with hesistation when i blip the throttle. In neutral and when i try and rev match. Ive checked o2, spark plugs, tps, wires, coilpacks etc. I have a datalog and i had the issue while datalogging if someone could take a look and tell me what you see? Something definatley isnt right and i feel its the tune.
