Ive had it peaking 15 then 14psi flat to redline for awhile now and with the plenum on and no adjustments it hit 21psi very fast...I use an mbc so I can easilly drop the boost down to stock level, so I gave it a few turns and it now hits 15 again and settles to 14ish. So same boost now but ALOT quicker to get to max psi the thing just wants to take off.The main thing I was concerned about was boosting too high, but due to the stock dump, I feel its keeping the boost down. I havnt touched the turbo... wastegate, accuator all stock.I'll upgrade the fuel pump and have it retuned.Sounds good, very similar to the type of plenums used by some fast rotary turbo's.

An enclosure containing air or gas at a higher pressure than exists outside. The air ducts, air valves and blower assembly inside the dash Also see intake plenum By the way Chris excellent job; looks great and if it performs well then even better. I admire guys that do there own thing with diy and show inititive. Brian
