Just came back from the dyno after boost install on Saturday....
99' civic si
.63 trim nissan t3 w/internal wastegate-stock @ 6.5 psi.
front mount i/c
dsm 450s
apexi vafc
custom equal length manifold
manual boost conroler
typhoon BOV
Car ran extremely rich with the settings in the FAQ only did 175hp with manual boost controler set between 9&10psi.
That manual boost controler will spike your boost to whatever you set it at but after that your boost will go to whatever the wastegate is set at. I set the manual boost
controler to 11psi. The manual boost controller peaks power at 6k rpm 221hp then it drops slowly to 210hp after the peak. An eclipse waste gate set at 10psi should fix that small drop in hp and give me an extra 20-30 hp. Car runs like a dream, peel out in second when it peaks boost on take off. So at 8k rpm I have 210hp I'm happy with the results. Thanks to everyone that answered my questions.

Re:Just came back from the dyno after boost install on Saturday....
The kind made outta a t fitting, 2 barbed fittings, spring, bicycle bearing, & bolt. I got the instructions in the FAQ. Bad thing is that the boost won't stay @ 11psi for too long cause the wastegate is set @ 6.5psi. I'm gonna get a gst waste gate and turn it down to 9-10psi. that way it's gonna boost at 9-10psi til 8k rpm. The car should put down a good 230hp at 8k since it's putting down
221hp w/10-11psi @ 5,500rpm. It peels out first when the boost gets to 11psi & 2nd. Ignition retarded 6degrees & ngk 4091 plugs gapped at .0028. It was definately worth all
the work to build it.

Well there are many things to fix that. I bet that your wastegate isn't tight enough. We had that problem on my freinds car. We fixed that and put the line closer to the manifold and got a turboXS boost controller. Now it hold 10 psi all day long.
