    had a browse through some of the threads on here and it seems that the most common option is a remap. mine is a 177 bhp variant so what could i expect in terms of gains?

    I will also be adding a k&n element and possibly in the future look into an exhaust system and decat. is there anything else out there to make my car a bit more special.

    Thanks

    Decats and DPF removal can help,but you'll still be able to get substantial improvements with them remaining.
    210-220bhp would be an middle range remap, but more could be made, especially with things like the decat pipe and no DPF.

    No need to change the airfilter, OEM one is huge and K&N ones can clog up the MAF sensor, either way there is no power benefit to be gained by doing it.

    It's the pipercross performance filter you need, not the K&N one,, on eBay

    Remove the DPF but keep the cat and get it coded out and replace the exhaust from just past the gear box and a performance back box.

    EGR by pass is a good move and link all that wit a remap.

    Regular oil changes will keep the turbo happy and the pipes feeding the turbo clean,

    I have a tuned and very quick 530d e60 and done lots to her so any thing I can hel you with just ask

    cheers mate, i have to say,i read your project thread the other day and your car is looking lovely.
    I have booked myself a remap for the beginning of next month so that gives me time to get the egr removed as well as the dpf
