Do these logs look OK? Boost leak?

    Hi,


    I tried the method of holding the revs at 3000 and check to see if the mass air flow sits at 10g/s. It initially peaked at just over 10, but as I held the revs at 3000 the value then dropped to around 8.3g/s. This made me suspect I have a leak somewhere.

    So I recorded the following logs this morning to see if I do have a boost leak. Could someone please tell me if my logs look healthy for a stage 1 remapped S3, as I not quite sure what I'm looking for.

    Many thanks,

    I read a post that for boost leaks you log 020, 031 and 115. I can only log 3 blocks at a time.

    Last week I logged 200g/s at redline, which I beleive on it's own is "healthy" for stage 1.

    Look OK to me. The engine isn't pulling too much timing, actual boost is falling behind requested which could indicate a leak under full boost.

    It's asking for 1.4-1.5 bar of boost, but only ever actually making a max of 1.38 which fades away much quicker than the map's request.

    Could be a few things, but start with a leak hunt.

    Thanks Welly. My Forge 007 DV is probably due a service. Could that be a cause?
