Installed tune and stays in limp mode...:shrug:

I get a soft mech. CEL, but resets itself after turn car off.

But, 50ft down the road, driving easy... jumps back into limp mode
(seems to hit rev limiter at 4K???):bang:

ANY advice greatly appreciated.

First try disconnecting your negative battery terminal, then reconnect after 20 min. so your PCM resets itself and then reinstall your custom tune..If you get the same error codes again ? try erasing the codes and see if they come back..If they do ? you'll then need to contact your tuning dealer, let him know about the codes and more than likely, he'll need to e-mail you a revised custom tune file for you to download into your X-CAL II
