I bought a skunk2 Throttle body. The Alpha 70mm and I'm having problems with the TPS. It's incredibly hard to turn the TPS sensor to make adjustments. Even with no screws in place. It's almost like the TPS doesn't fit in the skunk2 part. Works fine on the OEM unit. Just trying to calibrate the damn thing. Has anyone ran into this problem? Is there something else I need to adjust to make it work??? Please spare me the junk2 comments. I need useful information. I have a JG edlebrock manifold so I need larger than stock TB.

 

I have an alpha and it installed no issue. Didn't have to adjust a thing. I had a bin of old TPS sensors and had to try a few because I never labeled them, once I had the right one it was perfect. I think it came off a GSR. Try to email S2 customer service if nothing else works.

 

That's a good idea. I should have done that haha. I'll give them a holler and report back when after I hear what they say. Just wanted to see if anyone has heard or encountered the problem. It just fits really snug and then I have to hit the TPS sensor with something in order for it to turn any. My OEM TB was loose enough that if I loosen the screws i could turn it with ease to get the correct angle. Just weird.
