When you ran 93 was the tank empty or half full? For intake temps the cooled the better when driving they should be no more than 10-15 above outside temps in the summer on open road in the city they are going to be higher.

Step 1. crus at it.
Step 2. get a hammer.
Step 3. torch it.
did the pinging start with the tune? If not It could be a worn out timing chain and its advancing under load.
yea ran 93 oct a couple time back to back and on the log with 93 oct it dont show that much knock retard but still pings and it seems like the stock tune has more pep and has far as the timing chain motor has 44,000 miles on it could it be that already thanks guys for all ur help

So do you have efi live editor? If so why not just start from scratch and tune it your self.Originally Posted by silvyrado4.8

wish i did all i have is the scan cable software
I guess wait 4 me is not available to help you? I know If I had what i thought was a tune issue, the first person I would talk to would be the person who tuned it. Im not saying anyone is at fault. But Im sure The tuner could give you some insight. Im sure you have checked the basics? Sparkplugs, wires, vac leaks, sensors, SES light, ect...
