TPS upgrade??
 

Looked through several posts, could'nt find anything. Is it an improvement to use the FD throttle body and TPS? This is for an s5 NA.

yes, the FD TB is larger. but it wont fit....

if you have a S5 TII then you can use the FD UIM and TB when you portmatch it or get an adapter plate. then the TPS should work on the stock S5 ECU with only a rewire (i am in the process of this, manifold and TB are on, just need to modify the wiring loom)
S4 will not work as the stock TPS is narrowband...

but for NA, dont even think about it!
