It looks like throttle closing, but like i said if you want to be sure have your tuner provide a tune that locks the converter earlier to make sure. IF it already is then the throttle closed when it hit a load cap in the tune.

The Boss intake should carry power up to almost 7500rpm. What is your fuel system? You're pretty much at the limit up top in the rpm range with E and 125 shot. I would say a combination of that and the truck intake cams are limiting you. The Boss doesn't really make a big difference without GT cams.

All of the f150 Boss dyno sheets I've looked at do not carry power anywhere near 7500. Do you have any examples? Most I see are very much similar to my na dyno posted where they start to dip at 6200-6300ish

Filling the bottle back up and doing another dyno session next week. My tuner (MPT) wants me to get a log. Or do you guys think I'm at the level where a custom dyno tune is the way to go?

You need to change tuners before “more problems tuning” costs you a motor.
