Why not PM him?
Op are you saying that the car is a little hesitant under throttle, but only while cold? I have seen this before but it would always exist and wasn't only present cold. Don't recall what the outcome was but I don't think the person did anything and just let it be. |

My review:
http://www.m3post.com/forums/showthread.php?t=964892 Basically what's happening is when I initially start the car in the morning(been sitting overnight), initial start up is fine, so is the idle. But once I get going, in 2nd gear(DCT), it jerks as I'm accelerating from 2-3k rpm. It shudders like it wants to accelerate but the power comes in and out and creates a jerking motion. Coupled with an aftermarket exhaust(read:louder), it's audibly irritating. However, once i jump up to third, everything is fine. Cannot duplicate it again, even if I go back down to 2nd gear. In addition, this symptom is happening while cold start cycle is still engaged(obvious by the rougher sounding exhaust). I'm going to try and let it idle till the cold start cycle ends and see if it does it still tomorrow. Typically I turn the vehicle on and just drive off gently until it warms up. |

Then again, maybe that's all there is to it. I wanted to see if anyone had similar experiences before I ring the alarm bell and bring it to the indie shop. |
