Anyone who has a CTD in the 3/4 or 1 ton 07/08 Ram with 4.10 gears---------what does your truck tach at 70mph? How about mpg? Thx

 

I guess your talking about the auto. . .

 

yep

 

Well, my 4 spd auto tranny if I remember right at 70 mph I was running something like 2300 rpms and 75 was a tad over 2500 rpms. I have found the mileage is optimal in this range and once you go over 70 mph and 2500 rpms on the highway mileage falls off a tad.

 

I have the 6 speed manual and I believe its fairly similar.

 

'05 dually 2-wheel drive 6-spd 4:10 gear. If I remember correctly 2300-2400 rpm. 18-19mpg on B20 and AEM bruteforce intake.

 

mine is around 23-24 aswell.... i have read on here you get the best mileage around 2000rpms?!?! which brings me around 60 mph, but i can never stay at the speed for long[8D]
