a tune cant go bad from sitting, a tune is a program written to a chip, unless the hardware in the ECU or the chip goes bad, then that isnt your problem.

double check for check engine lights, make sure all your wiring harnesses have good connections.

Make sure you didnt pinch any wires or cut any during the swap.

boost leaks? is your boost gauge reading the correct amount? or is it reading low?

exhaust leaks? pre turbo?


oh and im going to make a suggestion for your posts.

Separate your points so it is easier to read. Granted the way i do it isnt proper english, it is alot easier on the eyes than a jumbled mess.
