Been a while, now with a rough tune, and it looks promising

I haven't been on here much lately. Part of it has been school. The other part was eating my words on head studs. Ripping an inch of threads out of your block isn't cool...

After tansferring everything to another block, with the proper studs, fast forward to today. Drove to P&L Motorsports last night only to have Jorge's(RiftsWRX) wife go into labor last night and him cancelling our appointment for today. I was able to get a couple cheap pulls on their Dynojet though.
This is uncorrected hp on a Dynojet, so take it FWIW. My boost control is all goofed up from my formally internally gated turbo pushing out the actuator arm to about 20 degrees from closed and me tuning around it not knowing what happened. I've since rectified the situation, but haven't had the time to go back through everything. I was running seriously short on boost across the board. It hit about 21psi at spoolup and taperd to about 15 at redline. This turbo isn't happy whatsoever untill its over 20psi so I have it spool to about 27psi and taper to about 22psi at redline, using all my injectors have.(650's)
The basics are:
EJ22T longblock
Wiseco/eagle, balanced
Delta cams, the hot ones
Bastard-child turbo (essentially a GT3071R, but with a 2.7mm smaller turbine wheel, .86 A/R)
TiAL 44mm
650cc Deatchworks injectors (SR20)
Homemade parallel fuel setup using an Aeromotive A1000-6
FMIC
Link Plus G2
Zeitronix
6mt
Hyper Single
Blah blah blah. If you want more details, look here. Note that a few things have changed http://www.mnsubaru.com/forums/showthre ... h+piddster
Anyways, the numbers are promising. With the boost tapering off so badd, the HP pretty much falls on its face. What is surpirising is how the power comes on so early just following the torque. With a serious tuning session, I'm pretty sure that I can make the power not drop 100hp in 2000 rpm. Also, I think there is a lot more torque to be made. The butt dyno said that before. This motor can take some serious boost without whining about it!
Finally, the plot...
