Let me know if you want the "20G or a stock 9 and I will sell you either one for 500! I want to get this 6262 on here!

The 14.7 is your atmospheric pressure, so you need to find out what elevation you're at and that will correspond with the proper value.

For example, I'm at 1000 feet and mine is 14.2.

I am at basically sea level but I will check the barometer in the morning and see what my local pressure is. Thanks for the formula.

I am impressed at this power level particularly because the car has no exhaust manifold, no intake manifold, and no O2 dump.

I am interested to see just how much the Turbo Smart wastegate actuator assists the set up. Which of these Turbo Smart internal wastegate actuators would be best? I am thinking the 22PSI, right?

I just got a JM Fab 02 dump to see how that helps this setup. Hopefully I get it installed Sunday.

OP, ironically, I have your setup plus a JMF 02 Dump, Curt Brown Ported Manifolds, and a Tial BOV and will be tuning this upcoming week, so stay tuned to see about what you'll be able to pick up with a few mods.
Did you ever get tuned? I am doing the JMFab O2 dump hopefully sunday and am curious how your graph looked compared to mine. I havent been able to log yet since I got the formula for the omni as I am working on doing parallel logging with my wbo2 sensor and I need the drivers for my serial-usb adaptor.

I did a pull today logging boost with the omni 4bar map sensor and I was quite surprised. I am running just under 29psi! I am very happy. The stock o2 housing I think is a big restriction. Tomorrow I will have #'s with the JMFab O2 dump. It is interesting to see a hump in the power on the top end but then looking at the log you see the boost jumps up a little right as the power goes up. I only hold about 21-22psi to 7K. I think removing all the restriction in the stock o2 housing will allow me to hold boost better.

STAY TUNED! Also this setup will be for sale soon as I got some $ so I will be working to get my 6262 on the car sooner than I thought. After getting the JMFAB O2 dump I was able to sell the stock nine to my buddy I originally bought it from since his 35R kit was a bust and needs some custom mods to fit properly.

Also today at my location I was at 14.75psi local pressure so my formula would actually be reading a little high for "boost" but it will give me a good reference for absolute pressure.

Sorry, I didn't see this post! Unfortunately I only ended up getting 250 miles on the car. I can't figure out how to get my AEM UEGO to log either, as it's not working through PIN 75. I need to make a serial cable but am unsure how to go about doing that.

Fingers crossed I'll get 500 miles this week and can start tuning!

This is coming along rather nicely, my friend. I am standing by to see how the O2 dump assists.

Thanks to you, I just bought a stock IX turbo to see what the "fun" factor will be for the short term. I am very excited.

Well I have some semi bad news. The 2.4l which had issues when I got it for basically free and I have been beating senseless has started to lose compression big time. I am going to have to rering it. Still runs great heat at speed but idle has suffered dramatically. Luckily this was expected and it will be
Much cheaper than a build front scratch.

Thanks a bunch. The powerband converted one of the biggest Mitsu haters I have ever met. I let him drive the car and he couldnt beleive it. I told him I plan on doing a 6262 and he was so ADAMANT that I not change anything. He said it is the most fun car he has ever driven.

The car is amazing even with a bunk motor. I got the motor basically for free knowing it needed to be rebuilt sooner or later. I am kind of excited to see if it picks up power with a fresh build. It is still fast but the idle is compromised. It is weird how a motor can basically be blown up and still make big power under boost!

Nice!! I kind of agree with your friend because a fun car on the street is what most people want. I dont think that a 6262 on the street would be so laggy that you would regret it. The top end would MORE than make up for it as long as you have 3k RPM of power from peak tq to whatever your redline is.

Power without a usable power band would suck, but if you have a good power band to make the car actually fast then its worth it!
