You may be surprised what it does going from 950 to 850. I'm running an SNS stage 3 cam which is pretty similar to yours. I had it pretty smooth at one time too, but I made some changes (one being idle dropped to 850 from 950) and now it sounds fantastic. I have a few vids in the new cams from Tick thread in the internal section. I'm running tsp true duals and it's LOUD

I am going to play with timing and the A/F as well. I know it's still running a little rich and the timing is up there (to smooth it out).

I'll drop to 900 and see and then maybe try 850. lol

I had mine running real smooth around 31 degrees or so, iirc. I'm pretty sure I'm at 24 right now. It still surges a little, but sounds great and runs pretty damn good. I'm still not done with it, but merely taking a little break before I fry my brain. It's all I've done since putting the cam in two weeks a go. It was all new to me as well, it's been quite the learning experience to put it bluntly lol

Yeah. Mine is around 28 degrees. It ran rougher in the low 20s but didn't lope.

Jake, Sorry to Hijack this thread but I see you have a FAST TB. I have the 92mm FAST TB. When I put it on the FAST 92 intake It didnt come with the bolt that goes on the back of the TB towards the top. FAST told me I need to leave this open but on the stock one it has a bolt through it. That confuses me... What should I do??

Are you talking about one of the 4 that goes into the manifold? Or is this a different one?

Yes. I have the four bolted to the front on the manifold but then on the back side of the tb there is a fifth hole near the top. The bolt goes in through the intake then into the tb. The stock tb has a bolt there. I just don't wanna plug it if it's not necessary. And I don't want it to mess with the tune being done tomorrow.

The 102 didn't have that?

And I don't recall my stock TB having that either?
