Let me know what you do to get yours to idle. Mines in the same boat, I drilled the tb 3 times and it still won't idle right. Blackbear couldn't get it to do right rather.
6.0, comp 216/220 lsa 114 with ls2 blue springs, full bolt on's, 78mm tb and stock intake mani.
Justin from bbp couldn't get it to idle, eve with all air flow it can have at idle. He told me to drill tb, with I have 4 times now with standard bits but its only helped when truck is warm. Lotta people say I don't need to drill but I'm not sure.
hmm, thats odd. My Truck ran fine with The other intake and TB with justin tuning it. The fast and 102mm is a pretty agressive setup. Shit your cam isnt that big even, I dont see why it wouldn't idle.
Im fairly sure Im gonna have to take it to Mike at New Era Perf in NY to get it nailed, Its just to hard to do via the Internet.
Found a local guy who has done alot of nice cars. He has a dyno that you remvoe the wheels and bolt it too...whcih blows cause he doesnt do 6 lug. Said he can tune it on the street tho. Gonna give him a shot, I got no time to trailer down the New Era.
