Ok this looks like a decent quality piece of equipment, easy to use, looks great! My mods before the reflash are Corksport DP, Mid pipe, Custom CAI, TXS boost controller at 18 psi and motor mounts. I went ahead and saved my stock map incase i gotta make it stock again and then i installed the stage 2sf revision 1.0. at firs the car ran weird as expected. i remember on my WRX the cobb reflash to a good 30min-1 hour of driving for it to learn everything. Anyway after driving and cruising on the highway for 45min-1hour the car was noticeably getting fast and faster. 3rd gear and up fell stronger and more consistent, the boost holds more steady than the ABC i was using. BTW i turned my boost controller off before he reflash. So far for the short amount of time i have driving it the car is noticably strionger in 3rd and up but 1st and second are noticeably down on power. Im not sure if that was done on purpose to help with wheel spin or what? So it works but im not happy about 1st and second anymore, Could be that im using a different intake or maybe it needs a little more time to learn or i can use my boost contriller to get an exra pound or two in first and second.
