Throttle closing??
Has anyone heard of the throttle blade closing during boost and N20? I added a small dry shot of nitrous to my APS TT 347 01Z06. I took it for a test drive while logging to check my AFR and timing to see how my IAT tricker circuit was working. I slowly opened it to WOT and it bucked a couple of times during the short burst at WOT. I checked my log when I got home and I show the TPS dropping from 100% to around 25-30% and going straight back up to 100% then dropping to around 50% and right back up again. AFR and timing were doing as expected. I hit around 15lbs of boost and was using a .036 dry nitrous shot. Any ideas? TC is not working at this time due to a faulty module, so that is not kicking in. My tranny in an A4 and is controlled via FAST/TCI controller.
