Default New Dyno #'s and some questions

452 hp/ 533 tq the graph looks super off. The dyno operator said the dip in hp/tq was due to where the converter locks up in the tune? Any input is appreciated. New Dyno #'s and some questions-photo100.jpg

Looks like the torque converter clutches are slipping, not putting all the power down.

Tell your tuner to provide a tune that's locks the converter at 2500 for Dyno testing and then measure 2500 to whatever.

I don't believe so. Looks fine.

Is that normal for the power to fall off before 6500 RPM, especially with the Boss intake?

He stopped the pull a little early, it didn't completely fall on its face up top. Here is a non nitrous dyno but on 93 octane, todays run was on e85 with a 125 shot. 369hp/350tq

Are these numbers relatively accurate then? Or is the higher torque number due to converter flash?

Your tune looks a little off regardless if you have a boss intake manifold. It shouldn't fall off to 7k at all.

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.
