here's my issue. I'm currently running the greddy blue box on my greddy turbo kit @ 7 psi. It runs alright, a little boggy at 7 psi, but I originally planned to run 10 psi on it with a walbro 255lph pump like some other guys have successfully run it here on H-T and turbod16.com. But in my opinion, that setup is only good for drag racing, as at half-throttle and lower RPM, it's boggy, but when you floor it it's fine.

Now with auto-x and road racing, I figure I'll be in high RPM and shifting quite often, so I'm wondering would the AFC hack be the better route to go for a more smooth powerband? or will the blue box suffice? For auto-x, I'll keep the boost low (6-7 psi) and focus more on brakes and susp. mods (and driving) than HP.
