dont worry about the TPS unless you have a idle that annoys you...the map though may cause the car to run rich/lean ...i would just replace it but before you do, check ALL of your wiring from the swap...and if a buddy has a p75 ecu laying around, throw it in and see if you get the same codes

did you have a si or a dx before the swap and was it dpfi or mpfi.

You may have switched the plugs. Try swapping tps and map plugs. seen it before.
