Why is my TRQ so low...? Well its not really low... just lower than I think it should be.
603rwhp and 506rwtrq
Here is my setup:
Procharger D1SC with FMIC 11psi at 7000RPMs
SW LTs Catless
Corsa Sport Exh
Comp 224/228 .581/.588 114lsa
AlkyControl kit
Upgraded Valvetrain
I have all the necessary fuel upgrades and whatnot also...
What would cause my TRQ numbers to be lower than most other Procharged applications? Could it be the fact that I run a Y pipe into a single piped exhaust system? I have been considering adding Cutouts before the Y-pipe but am uncertain if the cost would be worthwhile!?
Any thoughts on this or am I just worrying about something I shouldnt?

By the way whats your pulley combo to get 11psi at 7000RPM? Im seeing 11-12psi at 6800RPM with 7.25 crank and 3.85 SC pulley now.

ok first mick, your tq isnt LOW. second, its low compared to say... a magnason blower (roots) b/c yours is a centrifugal! your blower doesnt make much cylinder pressure at low rpm. thus it doesnt make tq. it also makes the car easier to launch at the same time as compared to the roots that makes its power at 3K rpms and holds it.
stop worrying. your setup is great. work on traction!
