I have upgraded my 6.0/radix set up with a Nick Williams 90MM TB. My PCM is 2002. WTH TPS do I need to make everything kosher. My stock TPS gets me 89% TPS. In searching on here it seems 2000 Firebird was the only answer I found, but...no further repsonses in that thread confirmed it.

 

The solution is to elongate the mounting holes on the TPS so that you can turn the sensor and alter the voltage reading and then do a TPS reset. Just in case anyone does a search on a 90MM TB Nick Williams ( NW ) upgrade from 78MM.

 

Sounds similar to the Accufab 90mm TB we have on our Z28. We used an older TPS sensor (similar to LT1/TPI) and did what you mentioned. Sorry I did not see this sooner, but glad you got it squared away.

 

Mine worked 100% with a stock 00 sensor first time.

 

I've been told this by a few people. Seems some are just a "cooter hair" off. I had to cut the setting tab off, but it's all good now.
