Just clear the TCM and the ECM... I don't think it's a big deal what so ever. See if it comes back. Have you had either out of the car?

ohh just clear it? is that my answer to why it is shifting hard and boost comes on late? i read on biturbos4.com that you can fry it what ever frying means in this situation.. but should i go to the dealer or just clear it. and if i do clear it will it perform to the way it should and better..

I didn't know that the car was giving you trouble.... Personally, I would clear it and see if it acts better. If it doesn't, you can be pretty sure that the code will come back.... Then I'd take it to the dealer. Just my $.02

The torque braking trick can burn out some of the internal portions of your tranny if you're chipped.

The error code you have doesn't seem related to that though. If your tranny is shifting poorly, it may have reverted to 'safe' or 'limp' mode and resetting the TCU might clear it up.
