Randy,
I think that the dyno # is a base for reference in tuning. To get meaningful data, you need to re dyno on the same machine everytime so it is consistant.
I really didn't care if it made 350...I just wanted it stable and safe.When we started, my base dyno run with the Vortech out of the box, pig rich program was right at 330 hp. So proper tuning can get you a lot of HP.
They got my AF line very smooth.

Damn with all those mods, u are still seeing 8psi??? I have heard ppl complaining about how with adding extra air flow you decrease the back pressure causing you to not reach the max psi.
Also, does your rattle at idle and did u change the belt?

It is just a small hickup in the inductive tach hook up that you see on this graph.

If you restrict your exhaust some, your boost might rise but you 'might' also lose a little bit of performance?
I guess it would be interesting to see how this works, especially after Esemes switched from his Borla TD to the Fujitsubo and he gained hp.
BTW, have you checked your belt to see if it's super tight?

Randy,
I've seen that a TD exhaust can be to big for an NA application.

I was told some TDs are to big for SC applications. Maybe adding the X-pipe will give just enough backpressure to raise your boost and still allow you to gain power.
I'm talking to Exhaust Depot to have a custom Stainless Steel tig welded X-pipe made for my Invidia G200.
