please help , i can not get my truck to idle

[emdub27]

i recently dropped a forged 370 cu in motor in my SS. it has a 216/224 546/589 114+3 cam patriot stg 3 heads. and is about 9.25-1 cr. i did a custom intake ( vic jr ) with a intake elbow to accept a 90mm ls2 vette tb. it has a speacial harness that allows it to work. (from the stock 78mm tb) im running a vortech blower on it also

my problem is i can not get the truck to idle at a constant rpm , it constantly surges searching for an idle. ive played with the throttle crack/idle timing and a couple other things. can someone please shead some light to me on this?

ive inserted my tune and a log from it.

IMO your idle is too low to begin with, however, you can reduce the hunting some by lowering your Idle overspeed/underspeed timing values. Your cam at that low an idle speed will easily see a +/- 25 RPM swing. If the over/under timing is too aggressive too soon it can chase itself around.
