Couple Questions

That is of course if I keep my foot out of it.

I can't give you specifics, but a custom tune will be better than the (same?) canned tune.

The canned performance tune is a 91+ octane tune, meaning you should only use it for gas that's at least 91 octane. If you ran 93 octane gas in it, You'd want to increase your timing by 1 degree. Bill would probably be able to make the 91 octane tune even more responsive than the canned tune. He would not try to sell you the tune if he couldn't do this.

Everyone says they DO get better fuel economy using a 91 octane tune over an 87 octane tune. This makes sense if you realize that a 91 octane tune is going to deliver more power (per unit of gas) than the 87. If you don't need that extra power, (keeping your foot out of it), you will use less gas. But, you MAY not save enough to make the high octane tune worth it. If high octane gas costs 10% more than 87 (about what it is here in Tucson), will you gain 10% or more in gas mileage? (You'd have to pick up that 10% to break even - I'd have to see a 1.55 mpg increase to make it worthwhile). I think this number IS possible, but I have not tried it.

I definitely picked up economy running the custom tunes over the canned ones. I added about 0.5-0.6 mpg while towing and close to 1 mpg on the highway when not towing.

Hope this helps.

well I settled for the one custom tune. 87 Performance. For some reason the order form lists the stock performance tune as 93 octane. I was only wondering because I wouldn't mind having the option to switch to the higher octane tune for more power. However if the stock 93 tune, or 91 if thats what it really is, gives a bit more kick than the 87 Custom Tune then I am set. I realize that either way I will get more power with whichever tune I get. And I also got the CAI after begging the wife so im sure that will help. Now I just cant wait for my tuner.

order was placed yesterday, how long does it usually take do get a response to know that they got your order?

From my understanding of the custom files is that Bill uses more parameters and they are tailored to your truck and its mods(dialed in). The way the gryphon comes initially is just like the edge. The one big difference is the gryphon is tunable and the edge is not.

I was just wondering if there was any confirmation at all. I sent the order yesterday and just wanted to make sure it was received. I know it says ships within 48 hours of receipt so was just wondering what the average wait was. Thanks.

oh, wait I just saw the notice at the top of the forum. That answers my question. Hopefully I hear back monday.
