So if there is enough fuel, why are we stuck at +60 rwhp? Is it a wall hit from limited fuel octane and the stock turbo size? Are these trucks MAF or SD Rick?

Rick posted a while back that, even though they have a MAF sensor, they do not use it. I've since verified this through testing.

We aren't "stuck"at 60hp. It's just that in order to stay within the efficiency range of the turbos, we are "stuck" at a certain boost level. You can time the crap out of things but that's where you're hearing octane limits. If there there is a load of fueling available, someone could tune for an e85 blend......but that's a pain in the rear because you have to mix your own fuel and you have to stay under about 3% error with the mix and the tune. Big turbos, big power.

4x4 screw at 120 mph w/what rear end and what RPM?
Mine was at ~2650 at 100 mph and I had a long enough stretch to run it awhile so it wasn't like I stomped on it and took a pic.
Since red-line is electronically controlled, what is red line - just wondering where/how guys are knowing the limit that have overridden the factory 100mph governor.
