You're probably on the right track with the timing. To double check yourself, the CAS should be generally in the middle of it's adjustment range.
TPS sounds fine.
Falling on it's face after 4k sounds like a boost leak. Check your couplers and vac lines.
Check the ECU codes with the LED and screw on the back.
i'm not thinking it's a boost leak as my internal wastegate (custom WGV), is set at 10lbs... i had a boost leak but fixed it, now it goes right up to 10lbs no problem... but before on the last motor with bad ring lands, it got to 4k and took off, hauled ass....
as far as the injectors, i haven't messed with them, i had them pulled from the old motor for about 30 days, kinda out in the elements (i know.. but i seafoamed em DECENT) but thats all i did, pulled em off the old SR and put them on the new long block... no messing with cams, i still need to install the HKS 264s if i don't sell em... haven't touched the manifold except to put the throttle body on.. has a 4" FMIC with new clamps and a few other goodies....
