Thanks to Jarrad of PDXTuning for the work on my Forester, Johnny Tran at JTran Studios in Houston for strapping down the car for a dyno, and Gillman Subaru SW for doing the tranny work and maintenance There's likely more in the car, but I wanted to keep it at 21psi. Car drives great.

It must feel good, but why so conservative? Nice setup...

It's my daily driver, and the car drives excellently. Didn't feel the need to add aftermarket boost control to go over 21psi.

Yes. The EBCS is still limited by the ECU's ability to read no greater than 21psi. I'd need an MBC to switch between 21 for pump and 24 for E85. I don't feel like running a piggyback ECU either.

do you have any plans to upgrade the tmic in the future? also seems a little laggy for a 68? as long as she drives good on the street - who cares!

I didn't know that, I always had a MBC

So how is this car boosting 24.5psi on stock EBCs? is it because of the pill?

Not laggy at all, in every day driving. I'm running the stock headers though. Might do those later to open up breathing a bit more.

From what I gather, he can't be using the ECU to control boost, or he's doing something else. I'm not knowledgeable enough on boost control to say more than that.

I use the stock boost control solenoid at 25-30psi on my 35r with my Ecutek stock ECU. It's magic though.

I take it Jarrad was in Texas on a tuning trip?

Because I bought the 6-speed as much for handling as I did for strength. I'm not in a number competition with anyone, and I'm happy with how the car runs, and I'll be keeping it for awhile. Brembos, exhaust header, and done.

If necessary. We'll put the wideband on it and run it, to see what it does, and make adjustments where necessary. The tune's conservative enough that it may take the header without any modifications...we'll see.

Unless I missed it, your still on stock airbox?

Not bad considering stock airbox, XT exhaust manifold, STI TMIC, and STI catback...our exhaust manifold is a bit more restrictive than the STI one too...

Actually, the power band will be improved on the bottom-end as well. Consulted with PDXTuning before considering it. Don't fix what's right, plskthx.

Yup, running the stock airbox, though it's not an STI cat back. It's a TXS Stealthback with a JDM Pink Forester STi axleback.

The Perrin wrapped headers that I'm picking up from PDX should give me a bit more torque across the board. Contrary to popular belief, in this scenario with my setup, I won't be giving up any low-end power.
