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.

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.
