7mgte hesitation *videos* help me

[ccguy]

so this started as a cel 52 i rewired it with new rg58 wire and it fixed the cel. the problem was this hesitation. as soon as the hiccup would happen the cel 52 would come on so i thought it was a knock sensor problem.
now there is and are no cel codes showing or stored.
but between 1800-2800 there is a hesitation that as you can see in the videos it just falls on its face like a car running out of gas.
i just replaced the TPS with a new one and set it to spec. and it still has it the same as before. it is driving me nucking futts, i can open the throttle and it will fall on its face and not accelerating. but if let off and gas it again it sometimes will blow right through the hiccup range.
i can feather and rev it over the 2800 rpm it runs strong and no problems are evident. like in one of the videos.
-i do not have any intake leaks that i found by pressuring the IM from the first turbo coupler to the head.
-i have the oe fuel dampener on the fuel rail.
-the injectors are firing in a constant sequence when it is choking (listening through a stethoscope)
-timing is set to 10 deg btdc
