Well i go up to get the car dyno tuned and when they plug it in everything is going fine it reads the computer and everything. Well they go to tune it after my baseline dyno pull and the A/F is lean. So they tune it and we go again and it stays the same. So the guy does it like five more times and it doesn't move at all. I mean this guy did everything he could and it didn't move at all and neither did my HP. I mean it was talking to the computer and everything and went in and it didn't seem to hold the tune or something like that. Has anyone else had this problem.

 

Sounds like operator error. If it was communicating with the PCM and was uploading fine, it should have taken the program with no problem. If he is questioning if the upload is "working" have him like bump the idle up to 1500 rpm or so. Something like that will be obvious if it took or not

 

Well i'm not worried about operator error because this guy knows his stuff. He gets some serious gains off the edit. I was told by a couple of people that had probs with it too that when they had a power programmer that it could have left some of that stuff behind and that could be the problem. I took the power programmer out before they tried to do it. I'm bringing it to the dealer to have them reflash the PCM like it just drove off the showroom floor and see if that helps.
