Well first off what a pain in the a$$, I mean I am no mechanic and it's really not that difficult except for the two bottom o2 housing bolts on the stock one, I mean come on, especially if you don't have the correct tools, changed that though. O.k. post install big difference two reasons butt dyno, and boosting to 23 1/2 lbs. not tuned or mbc yet. My mods are apex'i intake, greddy Ti-c cb, tp, buschur dp-o2 housing-licp, gauges are defi's and I did about 6 runs to a 100mph and recorded them and played them back (the defi setup kicks a$$) very happy with my mods to date. Feedback and thougts appreciated especially why I am boosting so high?

 

I just installed the buschur o2 housing as well. I actually ported a bit of the wastegate hole where it comes into the main passage and I ended up running 1psi lower than I had before. Just turn down your MBC until you can get tuned.

 

The LICP is likely flowing better, and the stock BCS runs off the compressor housing. This means the boost system is still seeing the same amount of boost as before, but you've given the turbo more room to breathe, and that pressure is making its way to the engine.

With all those mods, you need a tune ASAP. Make a wideband and a tune your next priority

 

I actually don't have my mbc on yet and I really do need a tune bad, my wife and I are taking off to vegas so after that I will get tuned and install my mbc and walbro. This thing is already crazy fast can't wait to get it tuned. I just did not think the boost would be that high w/o a mbc and tune?
