I think I will look into 5startuning.com a little more when it comes to my v10 truck.

I got the EvoHT, it did exactly what I "needed" it to do....alter tire size, bump trans feel, modify trans shift points.

HOWEVER!!

The sites and the box lie.
There is NO custom tune...I can not modify trans pressures, shift points, lockup, ect.
You only get your choice of:
Extreme
Tow
87 Oct
Stock w/options
Economy

I tried all settings with only the simple mod of 31" tires.
Stock with tire size change - done, worked great
87 Oct, little better, liked it the most really
Extreme, where I kept the setting - not very extreme at all....no change in shift feel really, but had more pep. We set to Extreme in a truck I put shift kit once and it was crazy hard shifts....not this one.

It drives great...but going to call them today and see if I can wiggle the trans tune options out of them....seeing that was the whole goal! I am a transmission builder for damn sakes. It is an option upgrade for like $100....oghhh!

 

The only tuner that can write custom tunes for selected Edge devices is PHP. They only come with canned tunes.

If you want to do your own transmission tuning, you may be better off with SCT devices and their tuning software.
