On the HD300 tune (with intake and delete pipe), you should be making mid-500 HP and between 1000-1150 lb-ft at the wheels.

I don't know exactly how much this would drop over a loss of 8 lbs of boost, but I'm also not too sure how efficient the turbos are over 40 psi either.

Maybe that helps a little... maybe not.

mostly looking for a dyno run or something because i know before people were laying down to the higher end of 5s. just wanna see the difference in power since the new tune. i thought i may have read somewhere on the h&s forum that it made more power. could be wrong tho. cant find anything solid. thanks tho

Im with Doss. I dont think the loss of boost will hurt you. Im sure the turbos lose efficiency after 40+. After that you would want to look into upgraded turbos.

Sickstroke6.0 laid down 577 with hd300 and intake exhaust and I think he has 35s. Idk which tune version that was though. It was recently though.

Im not sure sorry. I just did a 40-95 roll with the new hd300 and saw 42 but it was little downhill. If I roll into it on the hwy in 5th I can see 46-47 psi.
