Techtec tune issue
My car e90 M3 was fitted with K&N and Akraprovic evo exhaust, recently bought a Techtec tune from the local tuner.
First impression, the tune was rough delivery especially experience pull back between 2k-2.5k rpm with mid and full throttle feels like fuel starvation. Initially I though it could the tune needed sometime to set in however after 2 weeks I am still experiencing pull back at 2.5k rpm with mid to full throttle on 5th and 6 gear DCT. I went back to the local agent to check if I got the correct tune, they put the blame on the Akraprovic and request me to change to remus (whom we distribute) and it will be solved and refuse even to have a look. Didn't believe Techtec will produce such poor product, tried emailing Techtec HQ all I get was a lousy auto reply and waited for 3 weeks without even a word. Is it true that Akraprovic is causing this flat spot or fuel starvation? |

The akra does cause a dip, but this can be rectified with changes to the inlet and exhaust cam, changing the valve overlap in that area to fix the issue.

Well the question to me right now is isn't Akraprovic suppose to gain power? Guess right now I get either trade the Akraprovic for something else (open to suggestion) or get a retune from others. Also I notice remus provides 2 straight through mid pipes instead of a cross pipe does that remove the flat spot? Advise please. Last edited by Absolut1M; 03-06-2014 at 06:14 AM.. |

Not supposed to have a H and X in the same pipe. I have always been surprised they did that. Luckily the tuners have figured a way around it.

We offered DCT included for a limited time. It is now a paid for option. |

Fantastic service from these folks. Even if they charge for the dct... get it, you will notice a immediate difference.
