The BMW M5 V10 is a monster! But its down low power band needs help. This is what VR Tuned does do the E60 super sedan. We alter the timing, fuel, throttle values to give the car more torque, better response, no CEL from race pipes, and a whole lot of power and pull! This local customer came by Vivid Racing to get his BMW flashed so we took care of him and even helped with the flashing process. Of course once he has the VR Tuned iFlash Kit, he can read and write between files as he needs. Check it out!
