I think it's my O2 but not sure, tell me what you think?

Now that I have all those mods on my car, when I get on it pretty hard and and then hold the clutch in to coast my car dies, if i keep it in gear it's fine but why does it die when it comes off boost...now I got a CEL, is it the O2???

The best advice is to run up to your neighborhood parts store and have them pull the code. Advanced and Auto Zone will do it for free.

Its a boost leak for sure. I had the same thing happen to my first talon. I was going down the interstate a mustang pulled on me so i was like hell no and I hammered down. I had to turn so I pulled it out of gear and it died while I was going around the corner at 30 mph, lost power steering and smacked into a cargo van. I had the same problem on the car i have now and i got hard pipes and it fixed it.

Your profile says you have DSMLink, could you maybe post a log of this phenomenon?
-Does kinda sound like a boost leak. A log might confirm it.

Just a heads up. This site really frowns on street racing, you're better off to not post anything at all about it. I had a post deleted recently because of it, and I was even trying to talk someone out of doing a 40-100 highway pull to test their car.

I'll see what I can do on the Link Post, I checked everything i could on the leak, tightened everything, whats the best way to check for one, and find out where it's at?

Here's a link to the pressure-test setup on VFAQ. I made one of these, but used a quick release fitting on the cap so I can just attach my compressor line to it directly. Works great. Pressurize the intake system to a few pounds more than you think you'll be running (just for extra measure), and then use soapy water on ALL the connections from the turbo to the throttle body. Bubble=leak.
