Comments:
I Absolutely love this car, HUGE improvement over the RS. Nothing but traction, loves boost, and gets descent gasmileage even using a SAFC to tune. My only complaints are the exhaust is incredibly loud on the interstate, hopefully tyhe catalytic converter will quiet it down, and the normal rattles that all Mitsubishi interiors have can be somewhat of a nuisance. I do general Maintenance, oil, plugs, filters, etc., and she drives all day with no problems, just as realiable as any car. *KNOCK ON WOOD*

Very concise Justin. Car looks good. I need to get a ride at some point. I rode in the RS, but definitely need to see what this thing can do.

[ScottyB]

very nice indeed. even with all those mods i'm sure you're just scratching the surface.

[WRXtranceformed]

I've always liked yours and DJs whips. Great writeup...and here's to a problem-free 2007 for you!

[HAULN-SS]

You shoul dget that thing on a dyno and get a baseline with everything thats already been done

[Goodspeed]

Congrats Justin, that car is a ton of fun...I can attest to how it gets up and goes, no muss no fuss the car is fast. I'll miss the tractor sound and dark tint though Can't wait to see it again!

[JustinG]

I definately wanna get it on a dyno, only problem is finding an AWD dyno, hopefully the shop[ in staunton with the AWD dyno is legit, im gonna try and check it out when i get back in the burg.

[D_Eclipse9916]

Lets tune her up a little bit before that tho Justin. Im starting to tune mine and id like to see what the difference between a s-afc tune alongside a dsmlink w/ wideband and 3bar gm maf sensor does. Even though you have a more efficient turbo.

[Nis01]

Glad to see those stickers are going to good use. :thumbup: Nice work, can't wait to keep up with the build.

Well within the next month ill hopefully be able to purchase a wideband, then ill be able to tune the safc through a wideband. We shall see though. I wish i had never sold my wideband off the RS.

AR Fab in Winchester has an AWD dyno. And I just happen to know a guy who works there. I've known this guy since the second grade, so if you want I can get in touch with him, and see if they can work something out. I know they are legit too, cause they did a lot of work on that Corrado that runs in GTS with NASA.

[Nis01]

^^ Agreed. AR Fab is a great group of guys. Within the last year they have really been opening up to the AWD market. I know they just put down something to the tune of 625 on a project WRX of theirs. If you ever plan on going up there I'll definitely be willing to bring the Subie up for some dynoing as well.

Do you got one semester left, Justin?

[JustinG]

After all that work....Cracked the valve cover, overtightened, although give me some respect i was being very very careful. New JDM TYTE VC should be here soon, same treatment will be given to it polished letters and black paint.

[JustinG]

Well, i was researching some widebands and called for a price from horsepowerfreaks.com, i dealt with them during my RS build up. When i was doing the RS i ordered some injectors, they happened to be the wrong ones, so i sent them back. I assumed they credited the money back to my credit card, i paid off the credit card a couple years ago. Well when i called and got the price check they asked my information, low and behold they hadnt credited it back to my credit card they made it store credit. So i ordered the PLXM300, and only had to pay 6 bucks shipping. Technically i bought the whole thing but it was 2 years ago, so ill consider it a bargain at 6 bucks. Should be here tommorrow, then let the tuning begin.

Here is the wideband i purchased..... <!-- m --><a class="postlink" href="http://www.plxdevices.com/M-Series_productinfo.htm">http://www.plxdevices.com/M-Series_productinfo.htm</a><!-- m -->

Also the new VC is installed crack free thanks to DJ, i wasnt gonna touch the thing in fear of over torqueing and breaking it again.

[ScottyB]

nice! heard many a good thing about the PLXM300.

[JustinG]

yea i had it in the RS, i liked it. One of the better units out there for the price. No logging ability, but an update to the current pocketlogger software will be taking care of that.

[JustinG]

wideband installed, A/F is lookin good, turned up the boost to 17.5 and had no instances of knock according to the safc and my a/f looked good, a little rich but still good. But my autometer gauge was reading 21 psi, either i got some nasty creep or the autometer gauge = poo

[D_Eclipse9916]

yay for 16g, boost creep!!!! We need bigger turbos and bigger wastegates...damnit, I said I wasnt going to spend any more money.

[Nis01]

Nice work Justin. I'm hoping its autometer gauge being crap and not boost creep. Glad to see you could turn the boost up a bit.
