hey guys,
2020 gt manual..noticed an odd behavior lately. When downshifting, say from 4th to 3rd, car rev matches just fine but when I let out the clutch it bucks/surges for a split second and then its fine. Its almost like letting out the clutch to fast on acceleration, but I'm downshifting. The only mod I have is a holley no tune cold air intake. I checked all connections, checked a/f ration, and vacuum is fine. I can't say I remember it doing this with the factory intake. Maybe I'm letting out the clutch to fast on the downshift? Or maybe to slow because of the rev match feature? My next step is to reset the KAM/ecu to see if that would help. Alot of people say to disconnect the battery, but could i pull fuse 60 which is the pcm fuse?Any other advice on what else I could look for or try?
