TII miss at 6k rpm
 

I've been chasing this issue for a few months, posted once but didn't get any answers, so heres the progress, and any and all ideas and help will be greatly appreciated.

So, this car is a GTUs with a swapped s5 turbo motor. Has emanage but I disconnected it in chasing this problem. So this is stock ECU tuning.

So at about 5600rpm the power seems to start falling off, around 6k a little miss becomes apparent, I believe it to be ignition related, as it will pull through it, just no power. It feels as if its continuing to get fuel, and my AFR stays the same, boost stays stable aswell.

A second issue is it won't idle, it'll drop to 900rpm for a second or two and then slowly sputters down to 400-500 and will start to die if I don't give it some throttle. I adjusted the TPS already. I don't believe this to be realted to the hesitation issue above, but thought it could give an idea.

Thanks, Eric
