I have a 2008 Ford F350 Harley Davidson Edition.
DC Chassis Dyno in Brownsburg, Indiana. Chase from Fleece Performance Engineering ran all dyno pulls. I have a Spartan 275 tune, S&B CAI, Flo Pro 5" exhaust (DPF delete), PMF traction bars (really smooth out tranny shifts)
I haven't turned up the tuner any higher, as I'm not sure how much the stock transmission will handle.
