Hi, this is my first post, I've been a F**d diesel tech for 18 years. I don't like the product I just work there to pay my bills. I've always owned GM products old and new. I recently traded my 05 lly for an 07 lbz. We got 3 of the new 6.4 powerstrokes in today and went for a test drive . I wasn't very impressed with it. I can tell you it's not gonna be fun to work on . One of my buddies works there and he loves F**ds he has a 7.3 w/ nitrous, propane , bigger turbo, & a custom program I raced him numerous times with my lly with an edge , intake , & exhaust and hurt his pride. He wanted to line up the 6.4 short bed 4x4 against my 07 dually long bed 4x4 lbz. First we raced from a roll and I beat him by 2.5 lenghts, next we raced from a stop and he loaded it to 20psi and I left at idle he beat me by about 1.5 lenghts then we raced from a stop and both left at idle I pulled 2 trucks off the line and it stayed that way. Overall I think the power is pretty close . The Chevy is a little faster . the F**d has alot of turbo lag . I'm glad I beat him everyone at work always give me s**t for driving a Chevy.

Just followed one home tonight, coincidentally it was an F-350 CC SB. He didn't want to run, smarter than most. Did like the finned differential cover.

Yeah, When the 7.3 di came out I was thinking who the hell designed this crap it took a few years to get right. Then the 6.0 came out and its still a piece of junk. Now the 6.4 is probably going to have its share of problems you pretty much have to pull the cab off to do anything to it.

The turbo lag was as bad as a 6.0, it started feeling a little better the more we drove it . You'd think with the twin turbo setup it would really come alive but it felt alot slower than a 6.0

So I can only imagine the nightmare working on it will be. So the twin turbo set up offers no more an advantage other than emissions over the single turbo?

With the 6.0 we were seeing 26-28#s of boost. The 6.4 we saw 33#s . I originally thought it the twin setup was to prevent turbo lag cause it has a small turbo feeding a larger one but it did have quite a bit of turbo lag. Maybe it is for emissions and this trucks got plenty of it . I'm scheduled to go to the training center at the end of Feb. so I'll keep you posted .

It has twice the turbos to spool so why would it be faster? The air has to go through one then the other and then the intercooler before it enters the motor.

2 smaller turbos will generally spool faster than one large one; if the setup is designed correctly.

Just to clear all this smoke, there is hardly any turbo lag on the new 6.4. I drove one around for quite a while the other day ):h but I understand that a die hard chevy man isn't gonna say anything good about the other.

Don't bite my head off, but is it true what another DP member posted about the gear ratio differences between the F-450 and GM 3500?
