Default Dyno Results: Flat Plate vs Divorced W/G

I wasn't sure if anyone posted one of these yet so here goes. These are the dyno results for the hp gain with a divorced waste gate downpipe vs a flat plate downpipe. The first graph shows my 05' WRX with a Stromung 3" flat plate dp vs a Stromung 3" divorced waste gate dp. Since I didn't get a chance to dyno my car stock, the second graph shows what a stock 02' WRX put down on the dyno vs my 05's final pull that day. The Ecutek dyno tune was performed by Ed from Brainstorm.

Mods:
APS Cold Air Intake
PDE Up Pipe
Stromung 3" Divorced Waste Gate Downpipe w/high flow cat
Borla STI 3" Cat Back Exhuast
Samco Intercooler Hoses
Progress Coilovers
Ecutek Dyno Tune

Mainly I've noticed the car pulls significantly stronger in the 6000-7000 rpm range now. If you're thinking about going with a flat plate dp over a divorced waste gate dp, check out these results first.
