compare this graph to any of the stock turbo graphs found on the TTZD website and you'll see that there is definite lag. you can definitely feel the lag. the way it goes is like this...

stock: 0psi...3psi... 6 psi... 9 psi... 12 psi...
(so for stock, it's a very linear building of boost)

gt2530's: 0psi... 1.5psi... 4.5psi... 5psi... OH GOD HANG ON!... 10psi... 15 psi... 20 psi. (so, there's a slow building of boost for the first 5 psi... from say 2-3000rpm, but once you hit 3000rpm it just rockets like crazy)

for me, 2530's are fine for the street. i drive in 2 extreme ways... either like a grandma, shifting at 2300-2500rpm everytime, or like a maniac (full boost). so, the dual natured personality of the 2530's suits me just fine. and they're right... you'll need racegas (or at least an aquamist system) to get near the full potential on the street, whereas the 500's run great on pump gas all day long. with pump gas, you'll be making about 50-100 hp less than with race gas on the 2530's.
