Ok so I have came a loooonnggg way with my swap. It use to bog and stutter really bad around 2500-3000 rpm. So much that the RPMS would not climb at all. It would boost but barely pull. After I reset my timing, the car seems to run much better, but it still bogs a little around 2800prms. Now it pulls great after I get pass the bogging. Also my car is burning A LOT of gas, it runs very rich. I doubt I have have any boost leaks. Anyone have any ideas? Or things I should be looking for?

Specs:
Redtop
Good CAS
Set timing
Good MAF
All coilpacks firing
Stock pump and filter
Full exhaust and turbo elbow

Car idles at 800rpm, doesnt stutter til abount 2800rpm. Stutters for a little bit, then gains rpm and starts to pull.

I do have a tuned ECU, I don't know what its tuned for it came with my motorset. I'm going to search for a local SR to borrow the ECU. That could be the problem.
