I guess you know that I've already given you my opinion on your problems as being in fact too rich, not too lean. In fact, symptoms such as backfiring, poor performace, low exhaust temps, and carbon build-up on plugs are all very common symptoms of a rich fuel system. The other extrme of LEAN conditions are outstanding performance, high high exhaust temps, and white, very clean spark plugs.
Someone may very well be telling you its lean through their own turbocharging experience. (I'm not sure why.)However, before you start tearing things apart such as your fuel pump and such, why not try to go on this assumption for awhile. It's vary possible that your FPR is faulty and/or the non-adjustable fuel ratio spring is turned in to tight on the FPR or it has been placed in the wrong spot along your fuel lines. (This may mean a fualty FPR) I really don't know which, but just try and keep this scenario in mind.
