Wise Guy; Probably multiple answers to that question.
Yes higher octane gas will help reduce the knock, but as earlier posters have said is that the edge will cause a lean condition with a cai. Your engine timing has been advanced if it is pinging!
I would just change the programmer. Contact them and let a pro help you out. http://www.truckcustomizers.com/prod...ford-f150.html

 

Can you play with timing and Idle RPM on the Edge Evo or do you need to have PHP do that?

 

I ran an Edge Evolution on my 2001 F250 Superduty with a CAI, Gibson dual exhaust and ported and polished heads. This was before Edge would guarantee it to work with a Superduty. At the time,all they would say is it was meant for a F150. I ran it for 100K like that before selling the truck and never ran lean or pinged.

 

This is gonna sound like a stuid question... but what is "PHP" and what is Gryphone, and can you explain "custom tunes" (I have the evo and recently installed a K&N CAI...) thanks

 

PHP is Power Hungry Performance. They take your Edge Evolution and put custom tunes on it base on the mods you tell them you have done to your truck.

 

I have an evolution on my 08 4.6 with a AEM CAI and haven't had the lean issue in running on level 2 with 89 octane fuel

 

because its a 4.6 and not an 04/05 5.4...

 

Soooooo......Does the edge just come with the 3 programs you select from or can you adjust timing and idle?

If I only have exhaust is there any reason to get the gryphon?

 

You can adjust all of those with the edge however with the gryphon you can get custom tunes for your truck to maximize power

 

So Gryphon is better, however, is it needed on a pretty much stock truck?
