Well I have checked just about everything I know to check. Going to get new exhaust gaskets to rule out any air leaks there cause issues. Nothings seems to be leaking, but I am still getting crazy fuel trim swings. Cruising AFRs of 13s and sometimes fluctuating. Gas Mileage is in the 15-16s where I used to be getting 20. Waiting to hear back from the tuner to review my log I sent and see if they have any Idea where I should look. Going to ask if I can get a tune for the stock injectors. That will help rule out the injectors.

I also noticed car is slow to build boost. Will build to about 7-8 psi, the last 2-3 psi don't really come on till near redline. Going to check my wastegate arm to make sure nothing has broken.

Car also doesn't run the same twice. Will run great, then turn the car off, turn it back on and it runs like crap. Ready to be finished already.

Edit: Log From yesterday. 8psi max boost. Was getting 10.75psi before the switch. Going to recheck all my couplers, check intercooler, check turbo.
