did some more tuning on the carb i got the carb pretty close a while back, so pretty much left it there, but still had a glich around 2200-2500 where it would not respond great, so i tried changing around jets, idle a/b's etc-just felt like the change from transfer slot to boosters was laging-i had a 6.5 pv in it, and the 2 bar map sensor told me i was losing vacume when i opened it up, so i figured the pv's gotta be working-well, i took one apart, streched the spring untill i got it to open with around 8-9 lbs vacume(i used a vac pump)
man, what a diff-it flat out pulls like a freight train now, just wanted an earlier shot of fuel-prob switch to a boost ref pv
i run a procharger on mine, so my fuel needs are diff than nat asp., but this LS engine def has required diff. tuning than any of my procharged gen 1 or b/b engines-even off idle, i had to step up to a more agressive pump cam
