Cat's With no acceleration!!! Whats this?

Hmm..
Not sure I want to fiddle with my engine and different shops trying to find the right tune. I prefer that the engine maker do all that. So all I have to do is drive and what ever else to customize it to me. But not blow hundreds if not thousands chasing something you may never get.

I still want to go drive this truck. Maybe it will be a 6nz

 

I'm getting sick of the few of you that can somehow draw a conclusion as to how I or any of the other posters drive or what we expect from a truck based on a few comments from us.

This thread is meant to discuss the different cat engines and how they pull in relation to one another as well as other engines.

As the OP of this thread I'm asking can we just stick to comments about that.


Thank you

 

I am not picking you out of the bunch and shurely didn't want to start some war. I'm merely trying to say let's talk more about the topic at hand.
I very rarely stand on the pedal as I'm am an owner operator. And I drive older equipment myself. I am not happy with my current truck for many reasons so I'm looking to change. If I can do better with acceleration particularly going up a miner grade hill it sure would be better. In my area it seams like they put all the stop signs and lights at the bottom of a hill. Hard on brakes and engine. ...
I thought a cat may have a better chance at this but I also do not want to chase some particular end result with no guarantee, especially when it cost money every step of the way.
My truck may not be running correctly or something causing the ishues I have but the 12.7 Detroit at 470 at times can take as much as 3-5 miles to get to 60-70 mph standing on it in the last 3 gears. This is only going up minor to steep grades while accelerating. Once you have reached speed or on flat ground it does fine. Like I said I have other reasons for wanting to make the change, I just need to make a decision as to what engine I want.
