I drilled the TB and did the set screw thing listed in my other post, added 2* timing all the way through, set the idle to 800rpms, and added a little more fuel. It is running better and idles a little smoother, but it still idles down to 400rpms and sputters when its in gear with the brakes on. Is it common to have such a problem with vacume? Would it help to put a vacume booster between the intake and the mastercylinder?

Thanks for any help guys, i really wasnt expecting tuning this cam to be a pain in the a$$.

 

Well since you called out big tex and parish, then I won't give any advice!! j/k
How big of a hole did you drill? What are your iac readings?

 

Its drilled to about 3/16. What are iacs?

 

Idle air control readings. Read that thread in your other post.

 

Do you have the ability to edit your PCM? You need to raise the IAC tables for in gear some. That should straighten it all out.
