Hi all, having a minor issue with my '14 ST2. I searched the forum and didn't see anyone having the exact same problem I'm having, so I'm reluctantly creating a new thread.
Since I did my latest set of upgrades I'm noticing a problem in the higher gears (4th and up) while the car is under full boost. It feels like a misfire as the car sort of 'pops' and briefly stutters while on the loud pedal. The car has a Roush intake, CPE lightweight intercooler, Ford Performance cool plugs, MBRP cat-back and the latest Cobb Stage 2 93oct tune with the intercooler and Stage 2 tune being the latest upgrades. The car doesn't throw any codes, doesn't idle weird, isn't showing any changes in temps/pressures/mpg/throttle response, nothing. I tried cleaning the air sensor in the intake and reflashing the tune, but it hasn't fixed the issue.
Does this sound like a misfire? Is it something stupid like the traction control stepping in?
I'm hoping the collective knowledge of the forum can help point me in the right direction.
