There is apparently little gain to be had using the smaller pulley with pumpgas, but that's not to say it doesn't work with it.

Yea, either that or you could use a boost limiter. So if your running like a 20psi pulley and had to run 91 crap gas, you could theoretically just limit boost to 10psi. More torque early in RPMs too, because your 20psi pulley would hit 10psi a lot faster than a 10psi pulley would.
This is just based on speculation & random bits I've read on this forum, so I could be wrong. But I don't see why it wouldn't work if you limited boost lower for pump.
