a/f looks decent this was its first time out since the rebuilt turbo., here are some logs, the car wont go over 5500rpm, the injectors go flat, the rpms go flat, and the car doesnt accelerate much at all. here is a log, it felt like the transmission a th400 was slipping yet the trans temp is normal and it shifts firm. any help would be appreciated

look for an inlet restriction to the turbo... what is boost doing?
boost comes in to the set amount on the boost controller. then stays their, the rpms dont increase. the injecotr duty goes flat. i dont get it. do you see anything in the tune?

Everytime I have seen something similar it was not tune related
transmission issue?

try uncovering the turbo inlet for a single pull and see what you get.
intake off didne help, it oullsbetter with lower boost it seems, the injectors goflat which is weird.
im lost please help, i did send the turbo out and precision rebuilt it. could it be a bad rebuuild?

well that's new info...
So it worked fine before, it was rebuilt, and now it has done it since the rebuild?
yes i sent it to precision. the turbo spins freely and seems to be working correctly. the turbo makes boost, even 20psi. i turn it down to 10 or so and it seems better. what could be wrong with the turbo?

Did ya try to run it with a charge pipe off? What about your fuel pump(s)?
no i didnt take the charge pipe off, fuel pressure is good, twin intakes -8 feed. i had the 88mm before and just had it refreshed. plugs are autolite racing plugs. all looked ok. i sent the converter off today to have it refreshed. its under warantee so no biggie.
