So I decided to jump and try the hybrid boost controller idea. Well to say the least this has been a bit of a pain to figured out. After tinkering with the maps ALOT, I managed to get it to pull up to 10psi without a bit of knock all the way to 7800. I will experiment with it a bit more today and see what I can come up with.
I have a bit of an idling issue at the moment and have to look at my fuel trims and see if I need to fix something I may have missed since I started this using a factory map... I also had to use half values as it seems I am currently out flowing the stock MAF...Time for a bigger housing....woo-hoo!

Hey guys subie nubie here just bought my 08 WRX and am about to order a Cobb catted DP and get a tune from a local professional other than that my car is stock. Would it be back for my car in any way shape or form or not recommended to pick up the grim speed 3 port? Thanks in advance guys

Absolutely not. ECBS is virtually required, really helps fine tune boost control and will enable you to request more boost, factory unit maxes out just over 20psi

Changing requires adjusting your ECU. You'll have to take it to a tuner or have them send you a map for you to flash.

If you can I would bring a tool bag and install your EBCS right in front of your tuners shop. Or like the guys suggested have them email you a limp map to get you there safely. and just a side note. You dont need the down pipe to benefit from the extra control of an EBCS. Just a proper tune will do.
