best WOT value

[Circuit]

I just put 94 in mine this afternoon and switched to the 93 performance canned tune. Here is a list of what I ended up with changing:

WOT Fuel: was already at 1.5
Timing: was already at 0.5 (should I bump it to 1.0?)
Speed Limiter: 110 mph
Shift Firmness: +10, +10, +4 (I like the firmer shifts.)

I noticed that my speed is off on my speedo vs the gryphon. I am going to use the calculator to find out what my tire size should really be set at just to make sure since my truck has the wider tire option of 255/65R17. Not sure if they are a different height than the normal stock tires which would give me an error in speed, mpg, etc.

Also, now I feel the difference in a tow tune verses a performance tune. The performance tune feels much more drivable to me and with the added weight of a full tank of fuel plus she doesn't spin the tires. I did one 0-60 and got 9.52. It decreased since my truck weights much more this time around. When I did it I had a full tank of fuel (love that big tank) and a load of groceries and goodies from a day of shopping in town.

Gryphon average mpg stayed around 18 but I used the pass button quite a few times to try out the response. I found it much smoother than the 87 tow tune.

The above is based on my drive home from town which is 30 mins, half on a hiway doing 70 mph and the other half on a county road doing 60 mph.
