I've seen several 240's make 275-300 on the 370's, but yes they are pretty much maxing out both injectors and mafs. I supect the mafs was maxed and that it's the reason it starts to lean out up high. I think the original poster would be fine upgrading to the big28 on stock boost.
I'm not recommending that anyone go plop in a big28 on their SR and crank the boost at all, it was just for referance. Every car is different, the same day we dyno'd a stock redtop with only bolt ons and 11psi that was hitting mid 14 AFR's.
