al at dynoflash is doing all the subaru tuning for buschur racing and his subaru tuning packages. not to mention he has tuned his own sti on ecutec with a gt35r setup on pump gas to 551 wheel as of yesterday on a stock bottom end with a 12:1 afr... seeing what buschur has put out with a 2006 wrx tr on pump and 23.5 psi... i dont see why an STi cant achieve higher numbers and run more boost as it has a lower static compression ratio (8.2 vs 8.4:1) but the same displacement of 2.5 liters. it should allow for more timeing as well... i think 24 psi on 93 octane is even feasable for the stock vf39 at this point in time.it will however probably be off the compressor map efficiency range.

as far as dual pumps it can give you added headroom when getting close to going static on the idc (injector duty cycle for those of you that didnt know). 860cc's will PROBABLY only need the one walbro 255 but dual intank pumps is just ballin and an added safeguard.
