No input on your problem, but you don't have to click the cruise off. Just mash the gas and when you're done let off and it'll settle back to your set point.

Just as I thought. Ni dice with obd11. I unplugged the secondary o2 sensor just in case. No check engine light thank God. I have lightly beat on it a bit after tonight's oil change, and so far I haven't had an issue, but that probably won't last.

I click it off due to the delay. If the acc thinks there is a car still there, it cuts power drastically until it thinks the coast is clear. Once clear, it gives you the beans.

Your tune is EQT correct? If so I thought codes could only be pulled with Cobb and not with Obdeleven and VCDS?
I didn't know that. I might flash to stock and retry it.

STFT are fine. HPFP dips a bit at the shift but nothing abnormal for an IS38 pushing that much boost. Also, he said his misfire issue was in gear in the 5-6k range.
What does it look like when stft is not fine? What's the threshold?

And again this morning it happened again. This evening I will be reverting back to stock tune to see if it still happens.

Unfortunately no. I want to try a carbon cleaning to see if it helps. If I keep this car till spring I'll report back. How many miles do you have?
