Dave, a friend of mine has an 07 sti. we have converted it to e-85, and we need more boost. it spikes 21-22ish psi on the data but tapers off to 18 on the big end and we can't get any more out of it.

Can you do anything with the stock unit and the compressor side? I was thinking that the hot side could stay the same, and we just needed a change on the cold side to squeeze some more out of it.

Your thoughts on the matter are appreciated. Thanx for your time.

not much you can do on those other than go aftermarket.
