What TB mod are you speaking of and what TB are you using?
Tb mod
HI GUYS,i did the fill and drill mod,its a pro products 58 mm,ive readjusted the valves,and double checked,for vaccum leaks,i just put the top end on,im thinking with the cam and the le heads,2.08 valves,combined with the true duals.that the port velocity might be pretty low due to the reduced back pressure? and needs alot more idle air?

That cam is not that big. Did you try cracking the stop screw a bit and keeping an eye on BLMs?

I wonder if the IAC is broken or stuck.
