New to tuning been watching videos and have a small understanding. Installed a chop monster cam into a 2008 silverado 5.3. Got it to where I can drive it but the timing table is not responding to my adjustments. any help would be greatly appreciated.
19th change added 5 degrees timing and adjusted fuel.hpt
You've got way too much timing in the tune. Might want to go back to stock tables and then post a log. It shouldn't ever need that much timing even if you're running E on a low compression motor.

WOW .. Just a quick look at your timing tables and idle timing.... way too much advance like Greg said..
I'm no expert like he is, but that's a lot of degrees !!!
Looks good to me, assuming we're talking about an old big block with open chamber heads and a 3/4"-tall dome on the pistons.
Dang, after reading that i had to go look...
Do the knock sensors get paid overtime?
It would have to be a new record
40 straight to -1 with a small change in airmass.
63 degrees I would think it might even misfire.
It might be a good idea to get a start up tune at least.

Your tune says added 5*. Here is a pic showing the difference in timing from a stock map to yours. Your adding 31* over a stock map at load and up to 69* at low rpm. I am not sure where you got that timing map but you need to go back to stock and work off that. Those knock sensors have to be working overtime!!
