Arguably the most controversial member of the tuning community, Shiv Pathak of Visnu Motorsports has managed to extract an extra hundred horses and 126 ft/lbs of torque from BMWs already potent 300hp mill. With just an exhaust upgrade and countless dyno-tuned hours with their new piggyback PROcede ecu setup, the BMW puts down 374hp on 93 octane pump gas.
More details after the jump.
When asked how it drives at this level, Shiv responds:
Geezus. Whereas the standard PROcede map would pull hard up to 5500-5800 and then soften up a bit, v2.0beta just rips towards redline. Power never seems to fall off. Drives just like a proper M-motor in the way that it loves revs. But unlike an M-motor, it makes simply staggering levels of low end and midrange torque. Truly an incredible powerplant.
It hasn't been easy for Shiv - upon beginning this project there was a bit of animosity from the established tuning community and the hater-ade was poured on in spades. There were doubts from many that the PROcede could function after the factory ECU attemped to relearn. Others spread rumors that he had blown up several motors during development. At the end of the day, nothing sells product like a dyno graph posting triple digit gains.
