8.1 power gains

Guys with access to chassis dyno's, or anyone with 8.1 experience.

What kind of power gains are you seeing with PCM tuning alone?

Do you see much of a difference between tuning an 8.1 in a 3/4-1 ton application or an 8.1 in a Medium duty commercial truck application like a motorhome?


I read somewhere that 50+rwhp gains could be had tuning the 8.1 PCM.
Drop in a cam and tune the PCM, I would think that 100hp at the crankshaft gain could had.

Whats the factory rev limit of a 8.1 3/4-1ton truck application?


thanks

peace
