Canned tunes - what parameters are altered?

[Mossyoakglock]

I am considering running the 87 Octane canned tune on my '08 Silverado 5.3L. I am currently only running the modified stock tune with AFM deleated.

What parameters are adjusted on the canned tunes, specifically the 87 Octane? I'm not looking for specifics, just things like TQ reduced by X %, etc. When I do it, I'm only going to run the 87 Octane tune with the TCM all stock and AFM off.

its not easy to say how much TM is reduced, but its pretty much out of the way, timing and fueling at WOT are optimized for best power, enrichment delay is disabled.

Thanks

So the 87 Octane tune nearly removes TM with no other changes? Right now, I'm running the same tune with TM Off. So, if just the 87 tune eliminates most of it anyway, I may just turn it back on.

all you have turned off with the mod stock is the tm upshift setting, which we actually leave on in the tunes, we turn the rest off....try the tune, you dont know what you are missing
