Car won't shift
Car won't shift Went to the track yesterday, and my car wont shift on juice. It use to on the 100 shot but yesterday on the 150 it wont shift. I moved my window switch to shut off at all the way down to even 4thousand rpm's and it still wouldnt shift. I have heard that alot of cars dont shift with nitrous but it use to so i'm kind of concerned. Whats up?
Do you know if the pcm comanded the shift , In not sure if you have access to a scanner or tuner that can read the data stream but that would be the first thing to do , determin if the shift was comanded , If not it would need to be tuned for that setup , If it was comanded it could be a transmission issue

thats it, I had the same problem but thats exactly what happened, like it was too fast for the pcm to shift, the actual transmission is fine. So deff a tune TA4EVR is what we have to get 
Well obviously the dyno tune would be best but . someone with a power programer who knows just what to tweak could probably get you going with a little trial and error
