Predator Perimeters ?

It's not the size wheels it's the tire diameter, what size tires do your have? I used the performance tune and then kept adjusting from there on the fuel and timing in the first two rpm bands.

Do you have the performance tune loaded? What octane gas do you use?

Yea i have the perf. tune loaded and i use premium (90 octane) gas...

If you want to add timing you will need to run 93 octane, or else you will get pinging. If I get some time later this week I will post where my tuning is now.

I am running 93 octane gas but I ping like crazy at WOT. I have the performance tune loaded. I also have a cat back and CAI. Any help you can give with the settings would be great.

I got no pinging on the performance setting, and have been moving the timing slightly, of course you only have slight adjustment anyway with the performance tune settings

hey hcvone...just wanted to know if you got a chance to check how your tuning is set up? Thanks

No I did not do it yet, but I have the truck with me, I will try to do it in the next day or two, it depends on the Father's Day shopping rush if I can get to it.
