Don't get me wrong the truck is not that slow it just is not as fast as I'd like it to be. I've been in faster but also been in slower. It isn't that slow it's just not as fast as I think it should be and after seeing 01DodgeRam360's video it doesnt' seem to be anywhere near that fast. The cat and 02 sensors are the only things I could possibly see causing it as they are two of the things I didn't change.

 

I've heard a lot of bad things about hypertech's just not giving up power to vehicles... try putting it back to stock and seeing if that makes any difference.

 

I can't honeslty ever remember it being much faster than this. If it was I don't remember it and I've had it since it had 53k miles on it. I would guess it's even faster now. Might not be but it never seemed that fast. The Hypertech doesn't seem to add a ton but I've never heard of anyone saying they lose any.

 

Not really the same thing, but mine is about like his... Just a touch slower.

With your 4.10 it should be right in with his.

 

When I built my engine, the guy told me that un-sprung weight is more critical than weight on the springs. You engine has to not only push/pull that weight but it also is spinning it. Go to a track with thoes big tires and get a e/t then put some stock wheels and tires then run it again. I think we all would be supprised.
