you guys are missing out on the part where i said "CLOSE" and by close i mean 100 HP off. at 17 PSI i was able to do 380 on a conservative tune.
this stock twins, stock intake pipe with filter, stock downpipe with 4 inch mid to twin 3 inch duals, FMIC and AEM EMS. id consider it bolt ons only for a rather cheap price excluding the EMS as it wasn't cheap.
if you guys come out to the slow motion dyno day you can see it make the power as long as my turbos arnt dying.
