    I am checking with our tuning department to see if the car had any other mods. I will post the answer once I verify it.

    I spoke to my tuner and the car we tested was stock but we recommend doing an intercooler upgrade with our tune.

    Yes that is correct looking at the market for other high end tuning compaines I think we are priced very well in the market place.

    JB4 is $479
    Cobb is $895 MSRP but can be had for less
    Bimmerboost Flash is Free although you need $179 cable to make it work.

    Im not trying to be a dick but that pricing is not going to fly on this platform. Plus its a bit of a pain to mail a ecu in to be flashed.

    4 years ago maybe this would have been interesting, now I canīt find the meaning.
    I hope you do not bother, but it's what we all thought..
    The flash bb is free and there are many maps to upload without cost.
    Thankfully, there are people in the community amending map for free, although you will always reward by paypal.

    I'd love to hear how they managed to make so much power on a 335is with just software when Cobb's gains were barely noticeable on my 335is. Also, minor correction but you have the 335is listed as 2010-11 but they kept making them until 2013, mine is a 2013.

    It's likely a typo but maybe they are just offering it for those model years.

    $1,500 might fly on the E9x M3 market (basically the cost of an ESS N/A Tune + Test Pipes), but for a Stage 1/FMIC Flash is way overpriced, especially for a platform that's used market price is $15-25k.

    LOL, I think you should do some more research on your competitors products, just saying.
