    So what do I need to revert back

    OK
    I know this sounds counter-productive, but here we go:
    I have a full bolt-on RS2 kit with no internal mods running a Mihnea remotely tuned chipset. Problem is it's running way too rich despite all the help from the good man a few years ago. Performance is poor on WOT and the lag is not good (4.5k rpm before any boost) for daily driving off the line. So my question is:
    I have the stock K24 turbo reconditioned and ready to go back on. What else do I need to change apart from the ECU chips?
    Just to clarify, it has the 3 bar MAP sensor, RS2 injectors, Bosch Motorsport fuel pump and RS2 Exhaust Manifold are the key bits.
    Can I therefore, just remove MD147 turbo, replace chips and all will be good? Or do I need to drop back to stock injectors aswell?
    My intent would be to get a stock homefry off Paul until I can figure out what to do longer term. (Maybe MOTEC as they can be tuned locally but that is big dollars)
    Thoughts appreciated. BTW, Current peak boost is 28psi so obviously K24 shouldn't be more than 19psi if I recall correctly.
    Cheers guys

    You'll need to swap chips, install 2.5bar MAP and drop back to ABY injectors to run nicely on K24 turbo - I do have a nice set of chips for that of course... ~280bhp and 420Nm. Peak boost on those is 1.4bar or 21psi

        If you remove your current 3bar MAP sensor and chips, will you be looking to sell them?

        If so, please let me know.

          Thanks guys
          I'm keeping all the parts. This is a temporary move back until I can afford to upgrade internals to support increase reliably!

          Can you PM me price for Homefry?
          I guess the upgraded fuel pump won't matter?
          Cheers guys
