Yes and I plan to get it tuned when i can afford it. I actually took it for another spin today and stepped on it little harder. I kinda baby the throttle cause the thing is a pig on gas. But when I step on it is more responsive but I do have 600 pound quad in back last 2 days.
I think I was just over my head thinking the 4.10s were gonna make this truck get up and go like a dragster. These wheels I'm running are pretty heavy I cant knock the truck it's never let me down

 

I'll be running 6.17 gears when I'm done

 

I think a tune will REALLY wake it up for you.

 

Yah its hard to find shops around up here that will tune a truck this old. I have heard about hemifever and flyingryan but I'd prefer to work with them in person then through email .

 

How big tires you running ? That's epic

 

Will be 44s or 47s. I'm going one gear higher for a little more umph. Tuning the truck is hard. The only two "good" people I know you already mentioned
