but i think if you want to go into high boost levels (like above 13ish) then you need it or else you will be WAYYY too lean for that much boost at some partial throttle level

yes, get the dezod black box! i can build up pretty much full boost running an AFR of 14.7. regarding the tune, assuming the tune is the same or similar, im running 11.0-11.5 under WOT. im waiting for my greddy support tool to try and smooth up the fuel curve tuning off of MAP. btw, im still on stock clutch at 26k and boosted for about 2k and it feels fine to me.

would a catch can on the pcv not lower them enough?

so for people running low boost, like 8 psi, they are better off running 14.7 than 12 (powerwise, reliability wise 12 is better... but there is so little risk running 14.7 at such a low psi that i dont think the black box would benefit these drivers much)
please correct me if i am mistaken though!

14.7 is not the ideal fuel ratio for boost.
12.8 would be ideal for most applications for the highest HP but with higher compression motors like ours, it's still a little too lean. Running it pig rich will actually lower power, and increase EGTs as well. A good tune of 11.5-12.5 for moderate boost levels will make the best power.
You can get a little more power out of it if you go to about 12.8-13.0, but it's not that safe at all for our cars.
For those that have been driving this whole time, most of us either stay in low boost or floor it. I know many people dont go 50-60% throttle for extended periods of time in 4th or 5th gear without worrying about blowing something up. This just gives you the piece of mind.
Modding the PCV will help lower the EGTs, but no one has really been able to test long term results on this for reliability so I'm avoiding that for now.

so it ISNT good to drive 50-60% throttle without the black box since we are boosting but letting the stock ECU handle it???

Correct. Luckily the stock ECU pulls a good chunk of timing on part throttle so it's not instant death (if you will). Add in a good AF curve and it's a well run machine that should last a very long time.
BTW - Kit looks great man! Sorry to jack the thread. Let us know how it's been going!

sweet! nice to see another boosted tc in the islands. lookin good and i'll keep an eye out for you guys on the roads. i live around kaimuki area so if you see anyone shaka you'll know it me. 
also, ease of the install?
what shops can tune cars in oahu?
