    Hi Everyone

    Thanks for letting me join the forum and hope meet up with you guys at some point.

    I own a 2017 Cooper S F56 Gen3 2ltre turbo. At present it is completely stock, but the warranty is about to expire so I am looking at improving the torque and hp. I would really appreciate you guys advice on what is required to be fitted and where to take the car to get near the 270-300hp mark without putting too much stress on reliabilty.

    Have been looking at Dervtech and Lohen but is there anyone in Scotland.

    Cheers Alan

    I'm not too sure about mapping options in Scotland but you could always go for a JB4 tuning box. It's pretty straightforward to install yourself (2 connectors and an OBD plug) and you should see upwards of 270bhp without issue.

    Welcome to NMS

    As Ali has said you could look at a JB4 tuning box. Easy to install yourself. I had one fitted to my JCW Challenge along with a AWE intake and Airtec intercooler with great results.

    JB4 is a great hassle free option

    Cheers for the replies.
    I have been reading up on the Jb4 Tuning box and it does look promising. Am I correct in thinking that stage 1 does not require the OBD11 cable but stage 2 does.
    What is the difference in bhp and torque between the two stages?

    Would any other mods be required after fitting the tuning box?

    Much appreciate the help guys.

    Yep that's correct.

    If I remember correctly then Map 1 ups boost by around 4PSI over stock with Map 2 upping boost by a further 2PSI again (for a total of 6PSI over stock). If you install a JB4 without the OBD cable then it will default to Map 1 - the advantage of the OBD cable is that it lets you choose between a number of various maps. There's an option for Map 1, an option for Map 2, an option to turn things off altogether (and essentially revert the car to standard) and then a couple of options for custom maps that would be vehicle specific and programmable by a tuner. All of these options can be controlled via the indicator stock (and I think there's even an option to control things through your phone).

    Exact power levels can always vary but I reckon you'll see around 260-270hp on Map 1 with around 280hp on Map 2. The main concern with Map 2 is the exhaust gas temperatures (EGTs) which can get a little high. Usually you'd want to upgrade to a less-restrictive exhaust system (ideally including a sports catalytic-converter) in order to keep the EGTs low.

    The Challenge has the pro exhaust and I also had an intake and larger intercooler fitted when I was running the JB4. Easy to install and take off if necessary. I also ran mine with the Bluetooth attachment so I could control thing via an app on my phone that was great as you can control much more and it gives you the option to view engine perimeters as an added bonus.
