Well, the car is missing about 25-30whp IMHO but that's how my luck rolls with cars :) I'm fairly certain I have gunk on my intake valves again, need to run some pump gas/injector cleaner through this thing and see if it improves...should have done it before yesterday but meh, life's busy.
MitsuStyle.com spring dyno day yesterday! We were a little down on car count so we put my car on last and Shane @ DB Performance tweaked it a bit since it's been a year since it's been really dyno tuned. First pull was 467whp, final pull was 499.7:
This is a 1.0CF Dyno Dynamics dyno.

Walbro 400 + BAP + boomba rail + FIC 1680's are doing their job pretty well!

Still some taper, but we had some odd fueling issues so just left boost like so:

and dynojet/shootout numbers:

Got it on the road and afrs went a little leaner....so I realized last night that I need to really finish/re-engineer my air filter heat shield situation. I have a small shield that I made temporarily out of my stock exhaust manifold shield :) but the stock snorkel bypasses this and blows right on the filter....I have the primo intake and the maf sensor is placed right by the air filter, at the end of the pipe...I haven't looked at other manufacturers, but IMHO they should be moving the sensor back a good 6-10" from the filter inlet to avoid what I'm seeing.
I love having fresh air blow right to the intake but I guess it's causing problems. On the dyno afrs are rock-steady in the 11's, but I hit 13's on the street. Last night I had a eureka moment with all of this and I temporarily blocked the snorkel with my temporary shield and AFRs instantly dropped to where they were on the dyno.
So I ordered one of these:

We'll see how well it fits and how functional it is...if it's all good then I will get it and my new UICP powdercoated wrinkle black.
