my first impression was that the v1 is too loud what a high pitched sound also kind of slight chattery sound , is this normal ? It's like there something wrong intill your on your way then it sound is pretty cool. I bought a tuner kit from muscle motors added a steeda boost pipe 42lb injectors 225 lph walbro pump custom chip fom jms chips also ngk tr-6 plugs gapped to .028 still running stock maf . I got this all for $ 3200.00. The car idles fine and there seems to be no detenation. Also the car is a good bit quicker but I thought is would seem faster. the chip said the idle was raised slightly ,6600 rpm limiter, fans on @ 185, removed speed limiters ,total timing set to 17 * and wide open throttle fuel 9% richer than stock. Could some one tell me if this a very agressive tune. Of coures I'am planning a dyno tune soon possible

?
