N55 and N55HP?
while expecting my M135 sometime next month, I am doing some research on power chip
I found that there are chips for the N55 engine that boosts the power to 382hp so my question is, does the same chip work on the M135's N55HP? what are the differences between the N55 and N55HP? any idea? |

I think the M135i has the same engine as the 640i so if you find a tuning kit for the 640i engine, it should also work fine on tthe M135i engine.

It will depend on both engines being identical
It is possible that the M135 may have different valves, cams, compression ratio and different turbo boost rates You should check that they are identical before you chip it |
