only 153mm3 whats the deal?

[johnj]

I ran the truck on the dyno yesturday and logged it as well the the max mm3 was only 153 and would drop off on the high side of the pull. I have the limiters disabled whats going on? I havent changed any of the rpm tables but the max rpm of the pull was 3300

More than likely, not enough load.

The 6.7 fuels based on engine load, not just what you tell it to do. If load does not reach 100%, you won't see full commanded fuel

Did you data log the runs? If you did, overlay load and commanded fuel and you'll see they go hand in hand.

I've seen a 6.7 of two go over 160mm3...but like rich said...load is needed to achieve higher mm3 fueling.

Just curious how load is measured?

mm3 vs. rev-gain maybe? :confused:
