I've finally started to tune the turbo conversion in the '87. What I need to know is does anyone have a full range TPS on their S4? If so, could I get some details on it? A.K.A what did it come off of? how hard was it to install? what programming changed do I need to make? and other stuff that I might not have thought of yet. As always, thanks for any help.

 

check this link out from the microtech forum. It explains why you dont need full range tps. the microtech only needs to know if the throtle is at idle or not.
