I don't know if it's just me but it looks like it flutters a bit in the video at full open!

 

I doubt it unless the throttle actuator motor was weak. If this is only at WOT, with key-on/engine-off I would have someone hold the pedal down all the way while you check the blade position. If it is jammed against the stop, you may have to decrease the max throttle opening in the tune a few %.

Also while holding the pedal down, jiggle the throttle wiring around to check for intermittent connections. With the way the connectors are hanging there the movement of the engine on the mounts is going to be flexing the wiring near the factory connector. If there is an internal break the wire insulation will stretch if you grasp the wire a few inches from the connector and pull on it. The wires can break just from vibration over time.

 

All wiring is good. Cycled key on and tossed a turbo on the gas pedal to keep it wide open
I then then up and tugged on all the wires, wiggled, pulled, etc and the blade never budged. All wiring seems good, Throttle blade isn't held up on anything either.
I am thinking the blade is seeing flutter or else not open to the full 100% as mentioned, maybe back down the peak %, next step. If that doesn't work I am getting a 4 bolt to 3 bolt adapter and tossing the stock TB back on this thing!

 

the pressure trying to shut the blade closed, the tac module sees a inconsistent tps correlation in relation to throttle area in mm^2, hence shoots it into REP. You can map the throttle table, or you can switch back to a stock throttle body and you will be good.

 

I am switching back to a stock TB, done with hassling with this. Thanks for all your help everyone, maybe I will toss it back on later and try to get it figured out!

 

On the throttle body settings in tune lower the wot value from 100% to 98 and see if it works. This fixed identical issue on my truck.

 

Thanks! Will give it a shot tomorrow night, hoping it fixes it! If not, stock TB going back on

 

setting such limits will mess up any tps reliant tables, you would have to decrease every tps table for the relationship 98=100, so the tables would have to be multiplied by .98, the zero tables would remain constant as 0 times .98 =0 so they are unaffected, but you may fall into further problems where 100% tps is required and the only availability would be 98, falling 2% short and not satisfying such tps requirements. Stock TB would be safer, more reliable, and to be honest would yield similar power output ~10whp less at low boost.

 

Good advice! Waiting on my adapter plate to show up!
