mgtkr1 what ever the boost level it makes no difference pal. If its running lean the manifold would glow even if it didnt have a Turbo.

Riki my advise is always the same, i see an engine like a girlfriend. You wouldnt want her to be seen by loads of doctors, to give you a different idea on whats the problem with her. She would go to a family doctor that knows her inside and out and get decent advise.

I see the internet a little like wannabe doctors all trying to guess at a problem. When in fact the advise they offer may be well off the mark. Or even make things worse.

By all means listen to people and take in what they say, but choose wisely what you choose to implement.
