Twins tech question..
ok, this is probably beyond a search because of specifics. im trying to build a twin setu BUT i want a set that can hold loow boost now because of a stock bottom and later push 15-20psi w/o getting out of its efficieny range. i was looking at a set of gt25's but they seem a bit outdated.. any suggestions?
