Default Any one else have an APR chip that seems to have a mind of its own?

I have a 180 TT FWD with APR 93 Octane program. Sometimes the car runs great and some times the car is so sluggish I can't even get a tire scratch in first gear. I've especially noticed this to be true after I've been driving for a while at normal speeds then I start driving aggresively.

I've had the chip for about 3 months now and it just started happening. I've even tried reset the Throttle Adaptation and that worked for a few days but now it's happening again. I'm going to take my car into APR Houston (Bob's Garage) to get it checked out. I'll post a new thread after I get it looked at.

But, anyone else have this problem?

I have the same set up you do and have had no issues, I doubt it's the chip.

Maybe not but specifically the turbo doesn't spool up consistently which makes me think chip.

Additionally, resetting throttle codes on chip did help temporarily.

Could be the DV. I want to get better DV anyway. But what's the N75?
