    My W11 engine is equipped with a DDM cai, 15% SC pulley, 2%ATI crank pulley, RMW shorty header, Milteck exhaust, DT bypass valve, and a Jan Tune. In your opinion, will 380 injectors be beneficial? I don't plan to install a cam until my car reaches 50/60 thousand miles...maybe. As always, TIA for any help/information.

    I would think so. Although you may need a re-tune to take full advantage of them. Jan tuned your car for the mods it had at that time, probably not for future mods.

    If you are in fact running original injectors, then an absolute yes on the JCW injectors. MINI had to upsize on the JCW pulley, so that should show you how close to being at max duty the stock ones are.

    I would think yes, but you could also call Jan.

    Very good idea. He will be able to tell you if you need a different tune to play well with the 380 fuel infectors.

    I would double check with Jan since you are not adding a Cam. You will be limited on what you can do power wise because you have an automatic. 380’s are not a big deal since you don’t have a RMW head and cam.

    If you do get them you can run them without an updated tune from Jan. BUT, it would be very beneficial to have Jan scale them and update your tune since you can now flow more fuel.

    I have 380's in my car and it's an automatic. They do just fine. I had 550's but it seem to run better on the 380's
