So first problem is that i'm getting good fuel pressure but it's running on the lean side (14-15 at idle) and 13 at WOT with misfire (will be checking plug gap). Has good acceleration with an easy gas pedal but at WOT it bogs and misfires. I'm thinking the injectors might be bad, what do you think?...motor has FMIC, and T28 turbo but stock otherwise.

Next problem is the gear ratio...so my speedometer is telling me i'm doing 80 when i'm only doing 70, and it stays roughly around the same 10mph difference through the whole range. At 80mph indicated, the car is sitting at 3500rpm, it sounds a little high and has really good acceleration so i'm thinking that the gear ratio's were changed or it has the wrong speedo gear in the tranny? Any way to confirm this without tearing the rear end or tranny apart? What are your highway speeds and rpms?
