My boys 13 with stage 3 comp cams, cobra jet intake, and rev auto bfi is cammed out like a mofo. It's a super rare case Adam tried his hardest to tune it out but she's still lumpy as shit.
Thats because we put limiters in Collins car on the exhaust side. it has a tinie tiny lope. most people wouldnt think twice about. its not even aggressive enough to make people think its a ghost cam. If we wouldn't have put the limiters in it like we did with ronnies car. The car would have idled smooth as stock. Adams car idled smooth and so does my buddys with RGR regrinds.
Its all in the tune and if you are limiting the cam phasers at all...
