I am sure it has been discussed many times before, but...what are you seeing for typical boost at highway speeds and max boost under hard acceleration? Thanks!

Are you looking for stock numbers or from those of us that are tuned?

I am primarily interested in stock, but in would be nice to see the modded numbers for comparison.

When mine was stock I was seeing a spike of about 15-16 psi and then it would settle at about 12 psi and drop to 10 psi just before it upshifted.

What do you see with the tune? And what tune is it? Thanks

Stock peaked at about 14.5 and held 13. Tuned on Unleashed 93 performance, peak 19.6 and holds 18.5....at WOT.

On normally cruise I think stock was around 7psi and on a tune 12psi. The tune is worth every penny. I also see better partial throttle mileage the truck just moves easier w/o boost. That being said it starts to build boost earlier, too.

What's a maximum number you would want to see for stock at highway speeds?

Under normal cruising on flat road and no head wind? none, I would want to see vacuum (-numbers). Now if it was cruising up and down hills and not much wind I doubt I'd see more than 5 psi.
