Sorry like I said I didn't mean to offend just trying to offer an possiblity.

If it drove perfectly with all the hardware mods BEFORE you loaded the tune, the fix should be to simply reinstall the stock tune. If this does not fix it, there must be other issues. Reinstall all the stock hardware and load the stock tune. Verify the car is running correctly. Add back one component at a time, verifying that the car runs ok between each installation. Keep adding components in this manner until it fails. Then remove the last component you added and re-verify the car runs ok. You now know what caused the failure. If the tune is not for a specific mod then I would do this test in this sequence (flow chart).

Car has all stock components installed and you have verified it runs good.

Note: Test run the car between every step to insure it runs ok or it does not run ok.

Craezjo, dealerships historically blame any non-original parts. It's a pass the buck thing. Happens all the time with computers support people. Doesn't mean it really is the TB, just that it's the easy way out for the guys at the dealership, since they would actually have to troubleshoot the car, not just plug in their diagnostic computer and do what it tells tells them.

well thanks for the help i think im just gonna take out the throttle body and put the stock one in and hope that works and if not its probally the pcm, which would be alot worse. soooo if anybody wants a throttle body 70mm take mine lol.

One more thing, and agian just offering possibilities, are you loading the correct tune for the octane you are using?

craezjo

yup what im gonna do tomorrow is take out the throttle body and put the stock one on and if the car works then im gonna tune it then im gonna put the aftermarket one on. but i guess if that doesnt work then im juss gonna keep the stock one and sell the aftermarket one.
