Timing drops lower than commanded under boost.

Have an 04 Silverado 6.0/241/ls7cam/On3 turo kit. Running around 11lbs of boost. Spark advance chart is around 18* once boost hits but it drops down to 11*. Its not coolant temp or IATs pulling it down. I don't see where else its pulling from. Anyone have some history with it? Waste gate spring also suppose to be 6lb spring but jumps to around 8psi and creeps to around 11ish with no boost controller and feed line from turbo to bottom of waste gate.

Maybe I missed something in Torque management or something in Max torque table but max torque is higher than 11*

Burst knock?

I looked at your logs and didnt see anything out of the norm.

Try logging again but add Burst knock and flex fuel % and flex timing advance. I see you have it turned off, but maybe somehow its causing the issue.

Also, I have seen some strange stuff with segment swaps when they dont work properly.

If you raise the timing table 1 degree, does it also go up in the scanner, (proving something is pulling 6 degrees) or does it always go to 12 degrees?

Even if it were the flex fuel table, the flex fuel table is adding timing not pulling it out

So add every one of the various spark retard components
to your PID list (along with total advance) and see who's
bugging. Add the advance sub-components too (just in
case they are negative).

There's a reason, you just have to get the spotlight on it.

Did you email me by chance!?

Me? No I haven't emailed anyone about this issue

did you find a solution? similar issue myself..

looks like some timing is being pulled from iat and the rest possibly from burst knock

you need to adjust for burst and IAT for sure
