has anyone safely run the stage1 sport map in CA? I know the site mentions to run stage1 standard map in CA due to crappy gas here. Will running the sport tune retard the timing to adjust for fuel? my 335i is stock otherwise

My car was valet in mode for 2 days and it got incredible mileage. I am told that the actual mileage is better than what the dash says, but the dash was showing incredible numbers. I was surprised that, even under light throttle, the turbo is adding flow and reducing the vacuum. In valet mode, I believe that all turbo boost is bypassed.

I got my chrome trim vinyl wrapped last week so I loaded up the valet map for the first time. First thing I noticed when picking the car up was the exhauast was much louder. Then when I got on the freeway I wanted to see what happens when you hit the 4k rpm limiter. Only way I can describe it was similar to getting a fuel cut on my old STI. Its like your motor just ran in to a brick wall mid pull. I wish they just put a rev limiter at 4k, but oh well. |

I have to admit, the motor is really smooooth, and the sound is pretty cool too. It gives the car a different "feel". Almost wish I could temporarily remove the rev limiter and see how the engine pulls N/A.

No word on dyno #s yet though I think the Cobb&RB combo is going to provide the performance most people are looking for a big single to provide. |

you are not going to get more power because of that. just more safety.

I think RB mentioned somewhere in the 23 PSI range we would probably see diminishing power returns due to the stock housings. Will be nice to see that proven out, and what the real limit is on pump/meth or race/meth. I agree, a large single will find it's place with a crowd that has different HP goals for their car than a twin upgrade that is a quick bolt on for more power with much lower total costs. I would love to be able to hit 500whp on pump/meth safely. |

I'd love to see a dyno sheet on a 21psi through 6500RPM RB run... it would be interesting to see if the gains have began to significantly diminish or still on a fair rise.

Hello, is anyone running the Cobb Aggressive maps on a DCT N54 Z4?
If yes, any hiccups or possible issues (like the ones the DCT cars have with piggybacks)?
