S4 Discombobulator

Just got done installing my APR chip in my 2000 S4 with VM1 exhaust. Replaced TBB about a year ago, checked everything that I could think of and the chip doesn't seem any faster than the stock chip.
About 2 months ago with the G-tech did 5.6 with the OEM, now with the APR still do 5.6, did some runs switching to stock (via EMCS) and I got 6.5.
I'm gonna try some more runs tomorrow, maybe I'll get better numbers but I find this kinda odd.

Any suggestions why this could happen.

APR Chip vs. Stock is night and day difference...you'll definitly feel it.

Make sure you let the car sit for a couple of minutes before starting after you have triggered the adaptation.

I did an adaption once with some heat still in the engine and got lower power. As soon as I redid the adaption when the car was completely cold, it worked great.

Interesting, others tell you to do it with a warm engine hmmm.

Something is wrong.....if working properly, you would feel a difference.

It should be warmed up fully, and allowed to cool for about a half hour.

If there is any oil around the throttle body area, a leak is probably causing the loss of power.
