Alright, so I got the boost leaks in check and found out that my front o2 sensor is dead. I ordered a new o2 sensor and should get it friday hopefully.
I went out today and did a quick log of the GT30r at 20psi
short list of mods:
Apexi N1 catback and dp
K&N
2-216 FMIC
FIC 650cc's
Walbro 255 HP rewired
Aeromotive AFPR set to 43psi (hose off)
S-AFC
find all my mods on my webpage.
my Hi settings were 1k to 4k -28%, 4.5k to 7k -27%
Click here to see the log.
I am going to start leaning it out and see what the timing does, I really want to get the spool to around 4000 rpms or quicker. I definitely have a long way to go to realize the full potential of this turbo.
Any suggestions or comments?
Thanks guys!

You want to be at full throttle by ~2500 rpm in third to check out a turbo of that size. Additionally, the correction factor for 650s is -30%, if they flow 650 at 43 psi. So at your settings listed in the first post, you are richer than stock. Stock is about 9.5-10:1 AFR. Actually at such low airflow, that might be leaner. I would have to know what the airflow/rev was to make an estimate. For what its worth, anything between 10:1 and 12:1 is the same O2 voltage
