Took my exhaust side off my evo16g turbo to get the threads redone, put it back together. noticed I was running rich so I did a boost leak test, found out my throttle body and the part underneath it was leaking pretty bad. Replaced the gaskets. the part was still leaking so I ended up getting a fiav bypass plate. I also did take the tps off without thinking on where it was adjusted properly. At idle and cruise I should be reading in the 14's and under boost around 11-12s on my wideband. When I start it up now it'll fluctuate a little and then idle steady, but it'll be rich and cruising rich. i'll adjust the tps while the car is running till it'll start reading 13-14 on my wideband but after driving for a little bit it'll go back to reading rich again...

my ecu was flashed, tuned on e85 a year ago.

Any suggestions
