Anyone know how to convert to the gryphon?

 

I just did 0-60 in 7.74 seconds, is this good on level 2 custom tune?

 

I would say so. What exact numbers is your level 2 set on? Most of the time I am in the low 7's, but once in a while I will hit 6.7 or 6.8. I think it depends on the air temperature and how much gas is in the tank, lol

Are you 2wd or 4wd? Cab and bed configuration?

 

I have a 4WD extended cab. Used the tune in the beginning of this forum by bassackwards. My truck weighs 7200 pounds to lol.

 

Change to this and report back:


Level 2 87 Octane

WOT Shift
1-2 5000 RPM
2-3 5000 RPM
3-4 4600 RPM

Rev Limiter:
5400 RPM

Conv. Lock Points:
3rd Gear Lock -4
4th Gear Lock -6

WOT Fuel:
1.75

Shift Firmness:
1-2 6
2-3 8
3-4 10

Timing:
+0.5

 

WOT fuel seems high. What is good to get 16 mpg?I drive in stop and go traffic all the time and I am still getting 12 mpg

 

Stop and go traffic in a big truck will always get bad mileage. I drive 22 miles to work @ 55mph and get 16-17 mpgs with the above settings. I however, dont adjust lock/unlock points. You seem to be set on that , but I leave mine alone. I also run 91 octane and +1.0 on timing.

 

I'm not set on it I just heard that if the tc locks in at a lower rpm you will get better mileage

 

What does the timing do?

 

Is the TC locking earlier getting you better mpg's? Like I said, I dont mess with them. Why? I spent over a month adjusting them to lock or unlock earlier, all it did was make my truck shift crazy and erratic (I did a whole thread on this, since much wasnt out there on it). I didnt like it, so I leave them alone. Advancing timing with a higher octane fuel will increase performance.
