Ok I have 4" exhaust and a K&N but I doubt they contribute to the creation of HP much more than my gauges do. So the Bully Dog Stage 4 Torque Plate gave me 267HP... ... Going to add Piers 3K Govenor Spring Kit and see if Scott (MassDiesel) can time my truck (still stock whatever that is) and see what I get??? If Trans and TC holds out maybe 275? Dyno Day = Fun
