Good day bros,
So I installed a Whipple 2.3, 2.8 upper pulley, 60lb injectors, Mafia, JLT CAI, Accufab TB, and a KB BAP. A few weeks ago, my tuner sent me a tune to drive on until my dyno appt. The car at this point ran fine. I didn't get in to boost because I was breaking in a new clutch. In the way to the dyno appt, the intercooler pump went out. (Didn't find out until later.) On the dyno, the numbers were drastically down
So the tuner checked all paramaters and found the IAT2 temps at 150 degrees! That's when we checked and found out no circulation on intercooler. So we let thw car sit fkr a while to get a decent run to check the tune. So after another pull the car made decent numbers, even with no IC. I had to baby the car home becuase of no IC. It's a 2 hour drive. By the time I got home, car was running horribly!! I checked iat on handheld, 200 degrees so i figured the pcm had pulled all of the timing. 2 days later, I installed a new ic pump. I tpok the car out and hammered on it and during the run, the car fell flat on it's face for a second and then took off again. Weird. And now, its has a rough idle on start up, sounds like a miss but will come and go. Sometimes it runs good on taking off and sometimes it misses a little but only until after I get going them it straightens out. If I am sitting in stop and go traffic, the miss will return but then go away. So in the last 2 days, I have installed 8 brand new Ford coil packs and another set of TR6s gapped at .030. I am lost. I have tried everything I can think of and I can't figure it out!! The only thing left is injectors. Maybe a bad one? IDK and help would be greatly appreciated!!

I'm not a seasoned vet, but I'd take it back to your tuner or set up a datalogging rig so you can email them your logs to potentially identify the issue. Maybe the high temps while tuning threw off the tune?

How is the BAP wired? Some cars do not like post FPDM (which is how KB tells you to wire it). I had similar issues with mine. Swapped it to pre-FPDM wiring and all the issues went away. Went to 2 different tuners, the second tuner knows his stuff. Made 1 hit, popped the trunk and looked, said that's the problem, changed it and was fine for years before going return style.
