If you are not hitting somewhere close to these numbers you have an issue that needs to be addressed. So, stop turning up the boost to try and make it hit the whp numbers you want or you may hurt your engine.

17psi of boost, 10:1 compression ratio on pump E85
720whp

17psi of boost, 10:1 compression ratio on Ignite Red with 1/2 deg more timing.
770whp
An additional point is that boost PSI is a measure of resistance. 17psi on one car is different on another car depending on restrictions.

BTW, this isn't so much for you Spooler. Just an addendum to your thought.
