Without adjustments to fuel and timing, that 2-3psi bump in power is going to dig right into the margin of safety that BMW left in the tuning. Really not a good idea in my opinion. Especially for a car that runs so lean from the factory. But what you are proposing is easy to do. All you need to do is isolate the signal wire in the MAP sensor (simple 0-5v) and attenuate the signal a bit (perhaps 10%). -shiv |

A/F is for thermal management. Contrary to what people might believe, It really has no big effect on hp. DI has a cooling advantage over port type injection. Thus allowing for a more leaner mixture.. Cleaner burn and better gas mileage. Ignition timing is where you make the power. Hope this helps.
All the Best, Max |
