i have the same prob, also have a 383 stroker, full lunati kit with p/p 241s, 1 3/4 headers, .650/613 lift cam, with ls6 intake and stock inj. i know i need to def get bigger inj. and a fast but just wondering what the hesitation could be. Also the gas smell, it gets annoying when you pull up to a meet and your car smells like that lol.

Yea i need to deff get at least some 42#, im trying to wait till i find a good deal on some green tops, the shitty guy that tuned it told me it would be fine, i kinda wanted to stop him from tuniing it right there but he was pretty much done
