Ah hah. I didn't realise you had an FCD in there. If that one is clamping the MAP signal at 1 bar then that's the problem without a doubt.

Grab the FCD with the suitable range as mentioned by norbie and you'll be able to get rid of the SARD regulator. My bet is that the SARD has a higer rate than the stock reg, effectively masking the leanout in the top end-but not actually fixing the problem as it is due to the ECU stopping increases in fuel supply at 1 bar.

One concern I have is that if you bump the boost up further with this FCD, that as the MAP signal is clamped the ECU won't drop ignition timing out. In an extreme case you could suffer detonation-and the associated damage to pistons etc.

Have you fitted the wheels up yet? I haven't sent off the nuts yet as we had a major family medical catastrophy last week and I have spent my time waiting in ICU for the last few days (looking good now though). I'll get them off before friday though mate.

Take it easy mate
