I just put the hot cam in and it runs good but it tachs up really quick but takes for ever to come back down to normal idle what would cause this. I was thinking that it was either the heads or the stock header. I have hooker headers on order and the off roady pipe would this help and for now would gutting my cats help.
Thanks in advance,
