I just came across this TPS modifier that is supposed to be more than just a bandage for a bad TPS. The way it is described, it may work for me. But I want other opinions/advice before I invest $80 to try it out.

looks like its for bigger TB

I dunno, seems legit in a way, but for 80$, I would pass.

Which I've got.

oh, i thought you just had a bad TPS.

I think my TPS is fine, other than idle voltage being a little high. I've got a larger TB, and some tranny shudder under part load, around 40ish mph, as well as a little during shifts.

sounds like you are a candidate then. Sure it will work on SI cars?

That'* something I'm figuring out. As far as I can tell, it should at least plug in.

hey me too, there is a TSB on it

Hmmm, so TPS discrepancies have been linked to transmission shudder, eh? Interesting.....
