Hey gents,
working on a 2015 GMC with a 5.3 6 spd, slowly working on the tune but i am struggling to figure out why the timing under WOT is locked on 16* even though I'm commanding more in the tune under WOT.
I'm suspecting something to do with the torque model
see attached tune and log.
2015 5.3 6 spd Current tune low on timing.hpt
2015 5.3 6 spd current tune low on timing.hpl
Put TCS and stoic back then retest. I assume this is just a stock engine?
2010 Vette Stock Bottom LS3 - LS2 APS Twin Turbo Kit, Trick Flow Heads and Custom Cam - 12psi - 714rwhp and 820rwtq / 100hp Nitrous Shot starting at 3000 rpms - 948rwhp and 1044rwtq still on 93
2011 Vette Cam Only Internal Mod in stock LS3 -- YSI @ 18psi - 811rwhp on 93 / 926rwhp on E60 & 1008rwhp with a 50 shot of nitrous all through a 6L80

Thanks for the reply,
yup truck is stock.
now that you say that...
it actually did followed my timing numbers with stoic and TCS set how it is in the tune above BUT I added to the MAF to get WOT fueling closer, that's when I noticed the timing stop following what I wanted..
I could try bring stoic back to 14.1 and reducing maf back to see how it reacts.
I just may not have access to the truck now for a bit.
I have made the stoic change on more trucks in the past but never seen the timing not follow like this before.
