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.
