A couple Gryphon questions, what tunes and octane?

[PHS79]

Thanks Jack!

Here is what I was thinking of for tunes, let me know how you think this sounds.
Lvl1-custom 87 oct tow (with delayed up shifts)
Lvl2-custom 87 oct performance/mileage
Lvl3-custom 91 oct mileage (for 100% gas)

Do these sound reasonable to you? Anything that you would do different?

Paul, I think what you have there is fine. My only question is, do you really think you're going to use the 91 octane tune that much? Please understand you have to really run your tank almost empty before you fill with the 91 octane stuff to use that tune safely. IF, you are going to drive around most of the time with 91 octane (while you're at home), then it's fine.

And, there's no problem whatsoever in selecting an 87 octane tune with 91 octane gas in the tank - just don't go the other way, it can be hard on the engine to use a 91 octane tune with 87 octane gas.

I'm not trying to discourage you. I'm just telling you what I know Bill and Corey would tell you. Don't buy a tune you don't need. They don't want to see you throw money away any more than you do. Just ask yourself if you really need this tune.

I can tell you I've been VERY happy with my two 87 octane tunes.

The first 2 look good but are you really going to use the 91 oct eco tune that much?

For probably the last 6 months all that I have been running is 91 oct. Mainly because I found that I with 91 oct (100% gas) I have seen a 1.5 mpg increase, I went from a average of 15 mpg to 16.5 mpg.

Right now I am currently running my Edge on lvl2 because I didn't like the "lack of lowend" that lvl3 had. Granted the 1 full tank I did run lvl3, just to check mileage, and I got 17 mpg. But the "lack of low end" that the canned Edge tune seems to have, vs lvl2, is the only thing that concerns me about getting a performance tune. Granted the truck seemed a little funner to drive in lvl 3, once the rpms got above 2K or so, but from a standing stop it just seemed like the truck was a slug and didn't even want to move. Which leads me to another question:

Is there a BIG difference between the custom performance and the canned Edge lvl3? Also do Bills performance tunes have more low end power then the canned Edge?

From my personal experience with mpg and octane and price here where I live its a wash.
87oct is straight.
89oct is e10.
91-92 is 75% e10, so only 25% of gas stations have the straight gas. Only the larger towns will carry the 91-92 at their pumps.
The price difference between 87 and 91 is $.30-$.50 right now.
Alls I was offering was some personal reflection on why I ordered what I did. That's why I asked you what I did about the 91 tune.
You'd be suprised if you put a pencil to your figures and carve out some real hard numbers.
Some places you do get better results with mpg's and octane than others and it depends how you drive also.
JMHO

I've never noticed any lack of power in the low end in my two 87 octane tunes. But, I don't really "stand on it" there either. The power curves ARE fairly low below 2000 RPMs though in any tune, I'd guess. And, I've never used my Level 3 tune, so I don't have any basis for comparison.

You'd really need to talk to Bill about this, and that may be difficult in the foreseeable future. He would not blow smoke at you. The trouble with tunes when upgrading is that they're $60 each.

Using your gain of 1.5 mpg with 91, you're seeing a 10% increase in gas mileage. If 91 octane costs 10% or less more than 87, you would be better off using it. My guess is though, the price increase will be more than 10%.

Still, 91 does give you more power than 87 due to the timing increase and the more controlled burn, so if power is the governing factor, go for it.

You could just about copy and paste this entire thread into an attachment you could include with your order form. If you make sure Bill knows what your driving goals are, he'll be able to write the tunes you want.

Thanks for the idea, I am going to try and do that. I think the upgrade to the Gyphon and custom tunes will be my christmas present to myself

Thanks to both Jack and 88racing for the help!!
