Finally had time to make a appointment to get dynoed. I had to drive 1hr away to get this done because its the closest in ground dyno that I know of (my car is slammed) and it so happens to be a Awd Mustang dyno. Its 93-95 degrees when it was done 50% humid yes dyno probably corrects this but . The car kept making more power pull after pull as you can see and theres something funny going on down low that I should fix. Other than that im happy.

Fuel mixture was 4gal of e85 and the rest 93oct maybe i could do more on pure 100octane gas but i already had E85 in the tank plus it was one of the hottest day ever here in jersey so i wanted the E85 cooling feature that 100octane doesnt have. Once it drops to the 50-60 I'll re dyno on 100octane

The DME uses throttle closures for many things, buts always to try to fix something it doesn't like. Sees too much boost, will close throttle to reduce it etc, etc, if it is closing throttle its because it sees something it doesn't like

Please explain what you mean specifically. Throttle closure on the n55, as I understand it, has more to do with fuel economy than knock or anything like that. Even a stock car will gradually increase throttle on WOT and not see 100% until upper RPM. That's just the way the DME works in these things.

There is no other way to explain it, if the DME sees things it does not like such as overboost, knock, etc it has many weapons it uses to combat engine failure, throttle closure is one. An overboost will trigger throttle closures quite regularly, Tuners are constantly fighting them as they can sometimes be tricky to get rid of.
