When in 3rd did you do the pull from ~2500rpm up to redline?

I've just checked a log i did of mine (which as far as i know is stock) last October and I managed a peak of 169g/s at ~6300rpm

So you may have a boost leak somewhere. Next step would be to check the boost requested vs boost actual.

The measuring blocks I use to log boost pressure are, 002/115/118

Thanks for response, yea was til redline and I done requested and actual boost and they do match roughly when it spools it over shoots on requested but then settles

My mpg is averaging at 23mpg, that's me working it out, this is driving on decent roads without hard acceleration or braking, I would expect high 20's, anyone got standard maf readings or can tell me if mine is any good that would be appreciated

Forgot to say that's also on momentum 99 and tyre pressures are fine
