| GOODSPEED SL 550 stage1 ECU flash and filters | |
 | Unbelievable power and torque, without any sacrifice. Ecu timing, air fuel and throttle maps are all tuned to optimal levels while remaining safe. Under peak torque, the OEM air filter creates a loss of optimal flow (restriction at high CFM loads). The BMC air filter set allows optimal breathability for maximum torque.
The combination has been dyno proven, to make over 400hp and 400 Ft-Tq, on premium 93 Oct, and more on custom race fuel configurations. the filters are serviceable high flow filters for years of performance use.
