Read this whole thread. Seems that our tuners have alot in common. Spartan, Gearhead, and IDP. They all seem to have the small surge when doing small quick accell. When getting into it hard in quick about 40...tranny hunts gears. Each tuner has its pro's/cons. Looking forward to having c-slip on the livewire. I personaly like the livewire for gauges. At 45yrs old, I can see it well.
It seems we have an incredible engine, but the tranny lacks for great shifting no matter who or what tunes it. Whats weird is Erics tunes on my 6.0 I had was awsome! Why the difference? Who knows. Best daily driver for me..Race / Delay loc.
