    A local diesel shop is having an all access dyno day on Saturday and $50 for 3 pulls is too good a price to pass up. I'm going to log some data from the UCON during the runs and get a baseline.

    The truck as it sits now:

    URD MK3, C38-81, 70mm pulley, 80lb injectors, s2_800 cal file, full Spec-U headers and exhaust, 6 speed, 3.73 gears, 33 inch tires.

    Peaks just shy of 12psi at redline (6200) at 11ish AFR.


    So, submit your guesses now. Winner gets... NOTHING! :top:

    Best run was 383RWHP 401RWTQ. Video and graph coming.

    With those TQ numbers I expected more peak HP. Wonder if I have a leak...

    Kwigs wins. :)

    Those are exactly opposite of every MK dyno I have seen. Very interesting!

    Evidently UTune didnt notice when I pressed the sample button. So I dont have the log. :throwcomp: Such is life.

    Maybe I can figure something out from the graphs. They are supposed to be available on the website later today.

    Video (pulls start around 1:30)

    https://youtu.be/xkaKMDKbeCc

    It looks like I have a misfire up top.

    A lot of surprised onlookers. :laugh: This is a diesel place. I had the best numbers of the day for a gasser. Killed some gas V8s and made more torque than a couple diesels.

    Why do you think you have a miss fire?

    Never mind about the dyno file. Can't do anything with a SuperFlow file.

    A couple black smoke puffs in the video (before I hit the limiter). I'll check plug gap just to be sure. Coils are new. I thought you wanted a log from the UCON, my bad.


    Not unhappy with the numbers at all, especially for a daily with 150K on the motor. Just a little confused by the reversal of HP/TQ from the norm.
