Quick question ..
Putting the catless DP's on will lead to a check engine light, correct? If so, what is the fix for this? Does a fix exist? If so, what does it involve? Regards, Chris |

If you run the Catless DP's you will receive a CEL. In order to avoid this you can do two things... run O2 simulators or purchase a tune. The Tune is the easiest, and the added benefit is that you get some more power. |

It depends on the tune but you can expect a minimum of 15hp/15tq. Some N54's have seen around 25/30 hp/tq figures. If you take a look in the E90 335i Engine tuning section, you'll be able to see a lot of dyno sheets with the results confirming these numbers |
