    I was thinking about trying to save some data from a test run but unfortunately I don't have the gear to do it. Looking to buy a Nanocom or Hawkeye in the not too distant future though.

    MAP sensor has been removed is cleaned periodically.

    EGR is gone.

    F2 fuse is unburnt and looks to still be serviceable.

    Thank you kindly for the ideas, it's very much appreciated!

    have you changed your MAF for a genuine one? I had similar issue (no power under 2000rpm) and I have also checked everything, no success. Almost has given up, but about a week ago I have decided to try the genuine MAf (I had an Italian aftermarket one which seemed to be good according to Nanocom data) and I was really surprised feeling the difference after. Now my car pulls much better under 2000rpm and also accelerates better through the full rpm range. The acceleration from 0-100 has improved by about 3 sec.

    Well, with over 4000,000 on the clock, I came into a bit of money, and talked to Dwayne at MR Auto, organised to have my original ECU replaced with the upgraded one, that can be chipped. Put the car in, first thing was the MAF was stuffed. Was told in this type of upgrade, the MAF is the first thing they check. Well, new MAF , upgrade, I'm driving a different vehicle. Also done was the muffler was replaced with a sports muffler, and that little thing after the muffler was removed. I can't get over the improvement. Happy as.

    A bookshop is one of the only pieces of evidence we have that people are still thinking
