i have cat back flowmasters+just moded my plenum nice and smoth,will a reprogramer really wake it up

 

I have a Flowmaster, Edelbrock Air Hat, and APS pleneum plate kit thing, APS Transmission, and a few other things. I didn't have the runners cut down on the intake but then added a Hypertechit seems to help slightly and maybe a bit above 60 or so but it didn't make a super huge difference. It was worth the $160 I got it for but I wouldn't pay anymore than 200 for it imo unless you really want to have your speedometer correct.
