Granted the 6.7 will pull harder in the first three to four gears. When you get it in fifth and sixth then the 5.9 will out pull it. And yes my 01 5.9 had 353 gears and the 6.7 07 has a 373. In theory it should pull harder in sixth. Problem is the 5.9 has a single stage turbo and when you roll into the throttle a tad the boost would jump to 30 inches. And the 6.7 has the variable vain turbo. when you roll into the throttle on it the vane will not close and the boost will not come up past 17 inch's until you start shifting down and hammering the s&&t out of it. And the gas mileage just keeps going down down down.
You do mean PSI right?
psi? pounds per square inch.
OMG! LOL!!!!!!
Talk truck all you want - still can't change the fact my dick is bigger. (Why? Well, cause I am the first to see where this is going; I am the first to post it - and I can delete any others that say it aint true)
