Adjusted the APPS
 

I figured i would see how much the tps was off on voltage today and found that it was reading .344 , which should of read .441 , so pulled everything apart and got it dead on .441.:U:
Figured i would take it for a test drive to only find out that a few codes came up. (one was 500 and the other was a 236)

Do i need to clear these to see if it made any changes? Oh will the 236 stop me from building boost? Cause i am only hitting 18 lbs at WOT.:argh:

Hope this helps for the code that you have.
