I've been running an LT10s on my '86 N/A for a few years now and things have been running well, however my TPS is packing it in.

As a stock TPS from Mazda is $270, I've been searching for other options that could either do the job just as well for less money or better for the same money. I've seen that most people who go away from stock sensors are switching to GM or Haltech TPS, however these all seem to be on Turbo applications or on S5 setups with a full range TPS.

Seeing that it's to go on an S4 N/A, what do you recommend? Is a GM unit the best choice? Should I just order the Mazda one? Making something aftermarket fit is not an issue, however something that is plug and play tuning-wise would be ideal.

Thanks!
