hate to see you chasing your tail.the kb chip had alot of timing in it.throwing parts at the car wont make you faster.the car has meth and sounds rich as others have stated.you dont need to yank the motor to go 11's and as you learn the old stock motor is what you can play with yank it when you hurt it.
I agree w/Mr. Spool, as I'm sure the Bison and Pacearta. You have everthing necessary for the 11's except the tune.
As Bison and Pacecarta have mentioned the exh. housing, as the weakness in the combo. That would be an issue I would look at first and check the turbo bearings for coking? If the wheels are spinning free, no problem. If they are dragging it can cause an inconsistancy in the boost/rpm relationship. i.e. on one run the max boost may hit @ 2800rpm and the next run it may hit @ 3400rpm. It would be very difficult to tune w/that kind of inconsistancy. The alchy can mask problems as well, that's why it was suggested to turn it off, lower the boost and tune on the pump gas first. It will gernerally limit the damage to minor things while you are trying to learn what the engine likes in the way of fuel/timing. And as usual, you are tuning for no knock.
You are gaining the knowledge, but you haven't quite connected the dots for the "big" picture as of yet. We are all theere at differant levels, which is what this board is for.
