Question on 07's

[uhpilot]

I noticed that my new truck has a much smoother take off than my old one. It doesn't seem to have that "diesel lag", plus the turbo seems to pick up a lot sooner.

My new turbo gauge also goes to 40psi (with the red being 35-40). Seems like my old one had a range up to 30psi. I hardly ever got my old up above 20psi but I got my new up to about 30 pretty easy today.

Did they change the turbo from the 05's to the 07's?

Or is it the computer flash updates (didn't have any of them done on my 05)?

Or could they maybe have a different computer setting on this Southern Comfort edition?

I just don't remember my 05 turbo responding this quick or as much.



Also a question about the bigger tires......My door sticker calls for 75psi in the tires but the tires themselves call for max 65psi. When I checked them today they only had 40psi in them. So I put them up to 65. Should I have left them at the lower psi, or go with the max on the tire or my door setting?

Never had any tires this big before. I was wondering about MPG and the ride. Before I aired them up to 65psi (haven't driven it since) they seemed to have a little bit of a vibration when cold but got smoother as they warmed up. Is this normal also?

Wish I could help you, but my 07 was my first diesel....I believe the 07s have newer flashes then others....but I am not sure about the turbos.

My 07 seems to drive better than my old one also. Its weird they look the same on the outside but I would swear my 07 was a totally different truck.

My '07 is definitely quicker and stronger from a stop or a roll than my '06. I believe I read somewhere on here that the turbo is different on the '07s...I've never researched it. It gets better mpgs, too.

i had my turbo replaced on my 06 does that mean they put the new turbo is the updated one?

The later models were tuned for better low end turbo response, but that same tuning limited top end performance.

Why can't we just have both?

Talk to logan brrs3633 about having the best of both worlds on the 6.0 performance.

I meant from the factory. I have mine tuned for top and and bottom end, and sometimes side end to side end when the tires break traction when the go pedal is pressed without due care and attention.
