Tune or no Tune with Akra Evo?
I just got my Akra Evo installed and I was just wondering if it's worth having a tune? My car is still under the warranty and I would like to keep it that way :-) I did purchase the Delete-R to get rid of the CEL>
I'm loving the exhaust so far,the car already runs smoother and the gains are noticeable. I was just wondering if it would be better for the engine to get a tune. (running lean/rich kind of thing) Any advice would be appreciated. Thanks guys. |

You may gain some additional horsepower and torque from a file written specifically for the Akra though (ESS, Evolve and Powerchip have Akrapovic Evolution specific tunes). This power is gained by re-writing Fuel, Timing and VANOS tables to take the utmost advantage of the additional flow of the exhaust. |

Agree with BMRLVR, although I would go with the ESS due to you have the option with the tuner to go back to stock when you bring in your vehicle for service and then you can tune it back. That is one advantage to ESS plus you get updates sent to you via email and you can update it yourself.
Hope this helps |

I just put the Evolve tune on with mine. I would highly recommend it!

If you do go with a tune via ESS and flash it back to stock when you take it to the dealer...can the dealer tell the ecu has been flashed?

Because the Directflash stores your original file there is nothing that would trigger the dealer to suspect you have had your vehicle tuned. Just request stock RPM limit as a raised limit record is the only thing they can trace.

I'd recommend the ESS Akra tune - I ran this combo for a while and it was perfect!

Well guys,
Just got off the phon with my SA. If I go with Dinan Stage 2, and BMW installs it, the warranty will not be affected. he did mention, since I just got it installed, to break it in first without a tune, so when I do the tune, I can notice the difference. The Dinan doesn't add much HP (8-10 I think) but I guess safe is better than sorry. |

I have the ESS tune with my 2011 and Arka Evo, very noticeable differnance in power with and without a tune.
I am not worried about warranty with a tune, chances that a tune will cause some sort of warranty problem is very slim

Also, Dinan software was easy for me since my dealer is a Dinan dealer and for warranty purposes it made the most sense. |

I don't have the akra so my opinion probably does not mean much and usually I don't like to chime in on something I do not really know, but it sounds like you are really happy with how the car drives with the akra. You noted increase smoothness and power. You feel it is already improved. Therefore why bother with a tune? You may gain 10 more hp but at the end of the day is that worth your piece of mind about your warranty? (you mentioned that is important)
As far as the dinan tune, I believe it almost gives no power gain or extremely small, so why spend 1k on a tune that does not even up the power, if you already have a CEL fix? So with your options I think staying how you are is probably what I would do. If you do a tune, go with a better one than dinan but then your warranty potentially could be compromised-I know its slim chance. Or save the 1000-1200 bucks and continue to enjoy the sweet exhaust that you have! |

You have the ability to flash back to stock at any time and therefore there is no chance of a warranty being voided. So many of our customers are flashing back to stock and no one picks anything up. |
