[QUOTE="14ksstang, post: 14764167, member: 155145"] My update- I tried lunds 4th revision and still had the issue. It also acted funny while loaded. I gave lund the information I had and he told he had the same ecu in one of their cars and the tune was perfectly fine. He asked if I had taken the car back to stock before loading the new tune. I did not. I told him I would and get back with him. I did take the car back to stock loaded the 4th tune once again. Same issue. I haven't emailed him back yet but I have taken the 4th one out due to the drivability was horrible and my gas mileage went from 18-19 down to 15. I loaded the first tune back up for the time being. I'm trying to debate if I should even email him back. I believe the only reason he even helped with what he did was because the car didn't do it on the sct canned tune. If that tune didn't feel so worthless I would just be running it. Shaun from aed was the one that suggested trying the canned tune. I think him for that because with out that I probably wouldn't have received help. Shaun isn't doing email tunes yet from what he said or I would have just gotten his then. I tried emailing livernios but haven't received any emails bac. K. I am still debating on if I should try to just buy another tune or if I should just take a weekend trip and go get it on a dyno and have it tuned. As far as comparing the canned tune vs lunds for the issue he said he did that and there was no difference in the tune that would cause the rpm hanging. I'm not here to talk bad about lund because he has done awesome with others cars and my tune runs good other then the rpm hang. It's more or less a drivability issue and I'm probably just more picky then most. I do suggest and have told other on facebook pages that if you have this issue please report it to your tuner.
