Drove all the way back to the shop and it didn't go on the dyno >.< . They test drove it and said it runs fine. I'm glad I drove 3 hours back and forth for nothing.
I reload the tune and it runs fine. As soon as I come to a stop the car drops to around 500 rpms under idle and kicks back up to around 1k. After that I have a lot less power. It's like the ecu is not accepting my tune and throwing it into a limp mode. And I can get this to happen EVER time I reflash the ecu. I sent about 5 data logs to the tuner, but they are always slammed and they have trouble making time to check my logs out.
Not sure what else to do but bring it somewhere else which I don't want to do because shop hoping will get you in trouble. But I've been trying to solve this problem all year and now I'm getting annoyed.
Anyone else have an issue like this? If so what can I do? I really would like to enjoy the car once this year....
