Every single time I flash my PCM, I don't feel the difference right away. Is this normal? Am I suppose to wait a few drivecycles before I can notice the difference?

 

Its called the adaptive strategy. The computer, like a child, learns the settings and tunes itself up with your driving style. Drive the hell out of it and it will set up nice and hard, take it easy and you'll get better mileage.

 

what tune did you load??? 87? you should notice some difference in the shifting and the snap of the throttle right away. depending on the settings that you asked for on the tranny but you should be feeling something right away.

 

My tunes kick it right off the bat, no matter which one I have installed
