i have a 99 gsr with basic i/h/e and a vafc. after having the IM installed i must say off butt dyno vtec pulls a whole lot harder. low end has suffered though. it doesnt acelerate like it use to. vtec was set to 5500 and fuel was added when vtec engages..thats temporaryuntil i dynotune it next week. .my concern is while im on the freeway going about 80 and punch the gas, is it normal that it doesnt pick up as quick as when i had a gsr mani? when i downshift, vtec is loud as hell but doesnt seem like im going anywhere. another questions is holding the throttle at about 50% and then flooring it theres a weird sound of a whole lot of air sucking in, is that from the IM bc it wasnt like that before..
