Hi Guys, I have an 83 qtc with IA stage 2 and boost now set at 14lbs. My question is that recently when I start the car it runs real rough for a few minutes and then smooths out. It's almost like its bad gas, but I try to only run Chevron with a quart of octane booster 108 in each tank. Now this does now happen every time, but may be every other. Any ideas? TIA, Cleiter@AOL.COM
