Is it intercooled?
Add Methanol injection, this is a very inexpensive and effective insurance / power adder, especially if you do not have an intercooler (which i would recommend!) - Just make sure it is topped up, which is pretty easy once you get the feel for how fast it is being used.
You will find bigger gains by adding boost and retarding the ignition (to a limit of course).
It is very hard to say, perhaps your setup heats the incoming air more/less than another??? The best way to know for sure is do a tune with the targeted gas until you see a little knock then back it off (you might have to play raising boost lowering advance to optimize) enough to account for very hot days / shitty gas.

im running 16-17 psi on my motor with meth injection and the stock 4.5 inch twin intercoolers with 9.5 comp. no problems or complaints other than being able to smoke crotch rockets on the street
