The M1DH 140 HP Focus MK3.5 1.0 ECOboost engine is different and has the same compression ratio as the 100 HP and 125 HP versions.

Lower boost puts you in a better compressor efficiency and in return have a less knock prone setup that's also more consistent at variable temps.

Garrett Boost Adviser allows anyone to perform a turbo match quickly and easily by entering a few key parameters.

The only reason there is lower boost is due to the lack of enough air mass to put the turbo into efficiency range and cause it to pressurize the intake.
