What exactly is a "certified transmission" and what exactly is a road ripper 3000? Most heavy hitter 6.4 guys are using Elite built transmissions. Suncoast seems to be hit and miss. A stock 5R110 should be holding that power without issue, if they're using proper tuning...

 

A $7000 unheard of tranny haha!

I believe this story could be farfetched, or someone has too much bank, no enough brains

 

Spartan has the most power for the 6.4 from what i've seen!

 

I settled on the Mini Maxx after researching and asking the same thing...

 

what about xrt pro for 6.4?

 

I've got the SCT Livewire 9625or extreme tuner and I like it. 5 tune types that come with the programmer depending on what you want. I aint got custom tuning yet but I jus sent my device today to Innovative Diesel to get some. Guess ill see how that works. But I've had no problem with my CAT/DPF delete I have on my truck with this programmer

 

I'm running the H&S XRT Pro on my 2008 F350 Crew Cab. I chose it over the MiniMaxx and Spartan because it came with 10 tunes and that's all I needed. It improved the fuel mileage and performance.

 

i bought the Mini Maxx and i love that thing you won't regret it trust me

 

I have the H & S XRT PRO, i have set on the mild 80HP tune
