Anyone know the volumetric efficiency of our motor's with a set of vortec heads?

Re: turbo sizing app
I was expecting it to make a bigger change depending on the zipcode you enter. I pretty much live at sea level, I tried zip codes for Kansas City and Denver just for shits and giggles and I got a max change of 0.1
in the end, it appears my turbos will be just fine for my HP goals and can possibly squeeze some more out of them and still keep it streetable

Re: turbo sizing app
There are correction charts online. Word is that roughly 1psi of boost is lost for every 500m altitude climb after the waste gate spring rating is overcome. Not only that but air gets thinner so even though you might get same boost or overboost(because air flow sensor/oxygen sensor detecting less O2) you won't get same power and use more fuel. This is especially detrimental for superchargers.
