This is my first boost build with tuning. The truck has a hard bog when going into boost. Fuel pressure is staying at 58psi, it appears that timing is getting pulled way down, and i am running chasing my tail so its time i ask for help.
Lets start by its a lq4 gen 3, knock sensors are gen 3, ls3 heads, lsa blower with factory electronics, ls2 t/b, fast 65 injectors, lingenfelter fuel pump, and custom grind cam. If you guys would take a quick look and give some input i would be very grateful. I usually can figure things out, like i said its time for another set of eyes. Thanks

Also fix these:


Out of Range calibration summary: 08:37:00 am, Thursday Jun 18, 2015

EFILive Custom Calibrations
{A0001} Forced Octane Scaler Percentage, was out of range when loaded.
{A0002} Octane Scaler Limiter, was out of range when loaded.


There's trick to it: set the OOR cells to some value well within range, save file, exit tunetool, restart tunetool, set those same cells to desired value, save file.

I just thought I had this issue resolved, anyway its up for a needed weekend away from cars......but I just can't seem to lay this one to rest for a few days. I rescaled map sensor fixed b5911 and reflashed. Now during reflash the AWD denali's ebtcm decided it wanted to kill high speed line so I disconnected. First initial load it seemed fixed, but I reverted to previous concern. The engine free revs and idles great. With P0856 and p1689 now setting I'm wondering if this could be my concern. I rechecked rail pressures and AFR so that's fine. The other thing I keep in the back f thoughts are these redrilled ls7 fast 65 injectors ( no data injectors) but again afrs look fine when the timing goes to crap. Thanks again.

Im just wondering b5915 could be the problem or burst knock. Thanks again
