hello I was wondering if anyone could see anything that i should change with my 6.0 tune it seems to idle ok and runs ok. but just wondering if anyone could see any thing that should be changed to make some more power. it is a stock 1999 lq4 with 799 heads and a "hot truck torque" (205/210 .550/.525 115) cam and valve springs.

Don't you have to be running open loop, or are the exhaust manifolds not water cooled?
yes the manifolds are water cooled but there is a o2 sensor before the water mixesOriginally Posted by SiriusC1024

Oh ok. Not worried about reversion?
nope
Right on. Can't see anything wrong. Keep an eye on the knock sensors. Judging by your timing table you're already aware of what happens with 799's on an LQ4. It's a nice tune, really.
I'd be wanting PE coming in sooner and you better hope that fueling is on point. As well as making sure you can maintain 58psi of fuel pressure.
If you're running without a MAF sensor, just apply the 1 bar OS. This will remove the secondary VE and make tuning easier and will allow you to using the timing tables like normal if you have knock sensors.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
You could definitely lean into the timing a little even on 87.
Also the WOT fueling is set to be rich. A good tune should wake it up.. a lot of the tune looks pretty stock.
