can anyone tell me the range of boost most mild gn's seem to stop at befor knock steps in? i can get 20# in 1st and 2ed but about 17.5 in 3ed does this sound about right? i know every car is diffrent and i could get mid 20's with alky and good chip, but before i do that should i buy a front mount i/c ? a cold air kit? (i have a open k&n under hood filter now) i do have a te44 and 42's with a chip on the way. also looking for a good stall con. anybody's input is welcome thanks Terry
