> You just posted a video of you driving our tune with flat shifting turned on…but you’re not flat shifting. The sound you call “stuttering” is called a rev limiter. It is engaged by the clutch pedal. That’s what allows the car to be flat shifted. You’re taking your foot off the gas, then getting back on the gas before you’re all the way off the clutch pedal, so the rev limiter is still in place. It bounces off the rev limiter until you take your foot all the way off the clutch. That’s not a hesitation or misfire…it’s a rev limiter. Anyone watching that video can tell this. The switch for flat shifting is on the stock cruise control switch which is activated if the pedal is touched at all. That’s so you can flat shift by barely tapping the clutch pedal, which is the proper way to do it. We’ve been over this, but I’d be happy to go over it again.
