Ive been having the same problem a lot of people have after the stillen sc install in terms of the car wanting to bog down at low rpm or idle. Ive cleaned my throttle bodies, maf sensors and air filters along with a throttle body and idle air relearn procedure but the problem still persists. Im starting to think that if the problem isnt air related its fuel related but im not sure what the best course if action would be to eliminate the fuel pump as the culprit. Before i cleaned the tb's i would get the p1239 and p1238 codes which are both throttle body related and bank 2 specifically but now im not getting any codes which is obviously the hard part. Has anyone else had issues with the modifications required to the oem fuel pump?? Also my new tanabe revel afr gauge isnt working properly as it only reads 20 but again no codes For o2 sensor or anything for that matter. Im not sure if the two are related but i figured id mention it. Also the car runs great at normal speeds but when i slow down or stop for a light or stop sign it wants to shut off especially if the air conditioning is on which seems to make it way worse
