SR20 Z32 maf N/A or Turbo Lean

[NismoKnights13]

I got my car almost a year ago. S14 sr in an s13 the car ran perfect. Pistons, rings rods, arp studs, Disco Potato actuator is adjustable at 9psi I belive (no boost controller), nismo 555 on a Reytec non programmable... So it's like a chipped ECU. Ran 13 flat.

My problem is, it started running lean after I took out the motor to switch out the tranny cuz i broke my other one(the new one is also a POS)... When I dropped it back in it just started runnin lean...

I switched out the fuel pump to a supra, I'm thinking it's the nismo FPR(no fuel pressure gauge), or the Z32 maf... I'm not sure why it just started running lean after I put the motor back in.

I wan't to change the z32 maf but i was unsure if it matters if the Z32 maf is off an N/A or a TT... I was told by previous owner it's a TT maf, but if I replace it with an N/A will it make a difference? I want to knock problems off my list, I want to know that if i do change the TT to an N/A I won't be back peddling even if it doesn't fix the problem...

I've done research and they are both N62 and no difference. But a friend said that it'll be fine as long as the ECU is programmed from TT to N/A. But my ecu isn't programmable soooo.....

Oh and also when I open the throttle the Uego wont go richer than 14.2 that is the richest I've seen it go.. But when i need some throttle on the freeway and I am in 5th It'll run at 12.5 I don't punch it cuz it's running this way but when I do need open it up a little I monitor the Air/Fuel ratio...

The race that broke my tranny...
