Much like we have seen with the Turbo RR models, the factory 135 Crank Horsepower is under advertised. As shown with the blue line, these 135HP models produce just over 140 Hub Horsepower which calculates to 157 Crank Horsepower.
With the development of the WS165 MG1 ECU Unlock & ECU Bench Flash these models now produce over 160 Hub Horsepower, shown with the red line, which calculates to over 180 Crank Horsepower!
While we thoughtfully keep intake air temperatures, being non-intercooled model from factory, in mind, if monitored with a boost gauge, you will experience a peak boost achieved of 14 PSI, and boost will taper with an increase in intake air temperatures.
