super quick spool~WTF~
ok i just got done fixing the return line problem i had. so we drove it around the block couple times and notice that at 3000rpm on 1/4 throttle, its boosting 7-8psi, and at 3500-4000rpm on half throttle, its boosting 9-10psi. i dont think it shouldnt be boosting so much at such little load.
SETUP
d16y8 w/ CX TRANNY (Long-*** gearings)
t25~stock actuator
open downpipe
fmic
check vavles & fmu
what ever happen to stock 8psi settings? in the past i had a tiny rhb5 on my d15b7 but this is spooling hella quick. my friend said it could be the cx tranny and that its giving a heavier load forcing quicker spoolage
i dont know....help. this ---- is boosting way to soon with barely any throttle. probably a fucked up boost gauge...

my t25 spools pretty quick but not that quick.. your boost will be way off until you get a downpipe on it. i drove mine a few times open turbo and it wouldnt hold 8psi for ----.. once i got DP on it, it holds 8 PSI all day long

i know its normal for a small turbo to spool quick but i had a rhb5-open downpipe setup last year and yea~spooled pretty dam quick cause of its size but i was expecting more lag with the t25 but its spooling way quicker than the rhb5. hmmm...

Re:super quick spool~WTF~
Yep, there is definately a difference due to the "lack" of exhaust 
Last weekend I did a few basic dyno runs and wasn't satisfied with my results. I know this thing should be doing better. I started with the exhaust, and decided to remove it for now and run an open DP. I don't drive this thing daily so I won't be getting ticketed, but I can't beleive the difference in spool time, acceleration, and overall peformance of it. I'll definately be upgrading to a 3" DP and exhaust setup.
