I just installed my avc-r bc and i can't figure out how to tune this damn thing! I have an 03' bby evo with these mods: hks rs intake, rsr 80mm catback exhaust w/3" downpipe and 3" perrin test pipe, and a greddy type s bov. I believe it's set at 19 psi right now but spikes from 2nd gear and on at higher revs. I'd like to boost 20psi if it's safe enough with my mods and get rid of the spikes. Any help would be cool! Please!!!!!
