Spun the rollers yesterday

Well I went down and spun the rollers yesterday. Nothing has changed since I last went down and rolled an Uncorrected 358.

I decided to spin the rollers this time because I wanted to use the "Turn the key and defeat the speedlimiter" trick. The reason I did that is because it dawned on my that my last trip to the dyno the truck's speed limiter would kick in and kill me at 98 mph which is about 2750RPMS in OD.

To test things out I ran a run without turning the key and I rolled an uncorrected 351. So all seemed close. Next runs were done with the key trick and running to 130 MPH, which is about 3660 RPMs.

Run #1
387.8 HP
694.1 TQ

Run #2
391.1 HP
695.8 TQ

Just some info on the truck. Quadzilla 160HP Xzillaraider with a stock intake and exhaust. The temperature was 55 with a humidity of 26%.

Most everything else at our gathering were cummins powered trucks. There was one LBZ Duramax there that had an AFE intake and a 4" dual exhaust, with an Edge on the hot setting. He pulled a 478/1008!!! Those LBZ's are amazing!!!

On the 6.0 Powerstrokes if you turn the key it will let you run past the Speed limiter. It freezes the gauge in pre-test mode.

You know you are doing something right when the Ford dealers call you for parts.

Nice avator picture lol, its the truth.

You turn the key forward, the starter doesn't engage. I've done it before I got my sct, but supposedly it cuts off fuel to the injectors for a second which is bad. IMHO, you should get a tuner if you want to go past 98.

My truck is goin in the shop for what I think will be injectors next week, I don't think it is related to the key thing though.

I only did it for a couple runs on the Dyno. I'm not keen on 100+mph in a 7,100lbs truck so no need to get a tuner to remove the speed limiter for me.
