Ok so here we go iv got a 97 eclipse GS 2.0 N/T my TPS at WOT is only 74.5% I have tried to replace the TPS with a new one same thing and i have also replaced the throttle body and still only getting 74.1%. I have tried to replace the computer with a 420A out of a talon when i replaced the computer i lost spark in my coil out of coil 1-4 but 2-3 still works. Can somebody please help me out here i really need to fix this before i put my turbo kit on this car thanks?

Did you try to adjust the TPS itself??

Just adjust the throttle cable or get a new cable it could be stretched out. You can move the bracket back on the intake manifold too.

The tps on the 420a can't be adjusted and the the throttle opens all the way

What are you using to see the TPS readings?

I had the same issue when using a SAFC; it only read the TPS at around 75% at WOT. The ECU was seeing 100% but the SAFC would rarely ever. And that was after the cable was adjusted over and over again. When I installed MSnS, was 100% right off the bat.

Never did figure out why it was always reading lower, but as long as the ECU itself sees 100% it's fine.

Im using a wireless obd2 scanner and using torque on my droid to get my readouts

Are you sure it's opening all the way?

Have you tried a different OBDII scanner? It's not that I don't trust the readouts, I'd just want to verify the readings on another scanner...

HAd the same problem on mine and turned out to be a bad ecu. Of course I had other problems with the ecu besides TPS only reading about 75%.
