I had the truck tuned. I now know there is some issues. It seems that at WOT I get 83% TPS....I need to research that. Take a look at the config. I seem to be getting 2.8* KR...5.3/Front mount turbo/cam

83% is fine.. you need to log commanded ETC%.
Take this with a grain of salt, but looking over your narrowbands, it does seem your actually very lean.. Did you tune this on a dyno or street?
Looks like your around 5-6psi, if so, the timing your commanding shouldn't be giving you knock. Log your Air/Fuel and check back.

I tuned it on the street. I am wondering if I have to hook up the AEm wideband to collect Air/Fuel PID.
add 8% to your MAF table at WOT and take a log... get your narrowbands between 910-930.. This will be a rough method, but at least it will stop your engine blowing until you get your wideband installed.

Please excuse my ingnorance. I am having problems by adding 8%. Is this a paste special %. Not real sure how to do this.....
Sorry.
multiply your MAF airflow freq from 8000hz and up by 1.08..

Alright done. I will pull some data. be back shortly.
I changed MAF as requested. Take a look.
your not knocking anymore and looks like the narrowbands richened up. Looks like that was the problem, get to a dyno or configure your AF gauge properly to get your motor tuned right.
Lower your PE Enable TPS% and increase your MAP enable kpa. Your getting into boost and still in closed loop, not a good thing to do!
