Basic tune for 2011 5.3 NNBS w/o wide band
A family member is going to let me use his HPT for the weekend so I can tweak my Sierra and Camaro. I'm new to the AFM 5.3, so I'm just looking for what basic tuning I can do without the aid of a wide band. From looking through old threads, it seems most people just scale down TM, some disable AFM, and do some minor tweaking to the MAF tables. Is there anything else I should do?
It's been years since I've used HPT on my Camaro, so I'm going to have to relearn a lot of this stuff. I don't want to go overboard, but just want better drivabilty, more power under the curve, and possible better MPG.
Any one have any input or have a HPT file that I can use for this?

Target about 900 mv on the o2's at wot, the factory maf table will likely be a lil lean. If you are running 93 you will be able to run more aggressive timing, set the tq mgt to your liking. DO NOT DELETE ALL TQ MGT FROM THE 6L80!!! It will break your neck and likely a trans component eventually.....lol. No lower than about .25 on the shift times, desensatize the timing via tq mgt on the shifts. Shift points etc., the trans is where you can make or break a good tune on a 6 speed auto!
