it really depends on where your putting that 1psi on the turbos map. and the compexity of the setup, thier too many varibles to say really what you would expect, also you could dyno the exact same day exact same setup and see a 20hp difference or more. heres a couple of my expierances srt4 stock turbo 20psi 294hp srt4 stock turbo 22psi 303hp srt4 .50 trim 22psi 391hp srt4 .50 trim 24psi 429hp srt6 16psi 287hp srt6 17-18psi 310hp cummins 70psi 814hp cummins 72psi 820hp cummins 75psi 855hp cummins 80psi 909hp

1 pound of boost would be worth about 20% of the actual 5 pounds more boost you know you want to add. You say 1 now......
That's how it starts. I'll only do 1! next thing you know your at 22, and looking for more! That's where the term boostaholic comes from, I think!

Unfortunately the power increase vs boost pressure equation isn't linear. The more boost you add, the less you gain per pound of boost added. I went from 10 psi of boost to 18 psi of boost - and on my combo it only gained roughly 100 hp.
WOW...
I dyno 520 RWHP at 8 lbs boost and 690 at 14 lbs boost. On my set-up i'm not dropping off at all, however haven't pushed it to 18 lbs boost either... yet :-)

last I checked, 1 lb of boost is still worth 1 lb of boost.
....OR with the high cost of parts, labour etc likely every lb of boost is costing us around $2,000 LOL
