tune issues, car wont idle so here's the deal, hp tuners on a 5.3 ls with a ls6 cam 58lb injectors and a gt45r turbo. tuned with hp tuners, speed density 2 bar map. car wont idle, turns on idles high for a few secs then just shuts off. the iac is jumping around alot, i have no idea what it could be. i had a non speed density tune before and the same thing, but it would backfire and pop out of the exhaust like crazy, i tried to force it by holding the rpm's at about 2k and as soon as it was under load it would just backfire and pop non stop out the exhaust. can some one take a look at the tune and see if i did something wrong.
