Ok seems you guys are right once again took the truck out yesterday and out of the blue it started popping on high end tried over and over to adjust it out (WT 668) maybe there is something up with the throttle shaft, Any way I put on th WT990 tuned it and truck is back to a rocket ship what is really cool like krashkrieg told me I can spin all 4 at high speed in grass with those Hostile MTs on there! :eek:
 
The small tires are a great change. Plus it makes workin on the truck easier becauee it is lighter

The huge MT tires are like 25% of the MTs weight. :eek:

The MT tires are cool but they are a lot of mass to get moving.

I weighed the stock MT wheels and tires 2.5 lbs exactly each, I am going to weigh the new ones at work tomorrow

Yep. My Proline desperado with trenchers (rears) weighed 1.19 lbs.

I actually did the opposite and chucked my 990 for a 668.
I checked the specs and the bore and venturi are the same.
The only difference I can see is that the 990 doesn't have a choke and is a PITA to start.
If I'm wrong please correct me.
