Can the MAF sensor be left disconnected?

Can the MAF sensor be left disconnected, and what are the consequences of doing this? Is it adviseable to do it. What I thought was a turbo problem, is in fact a MAF issue. The car performs much better with the MAF unplugged, but are there long term consequences of doing this?

No I know they aren't that expensive, except I just spent £400 on a turbo because I was told it was stuck when actually there was nothing wrong with it. Thieving grease monkeys...

My own stupid fault for trusting the garage and believing what they told me. Never trust a garage. Should have just checked the MAF myself and a few other things before putting a new turbo in. Oh well, live and learn.

Leaving the MAF disconnected will cause the ECU to use some default values which would certainly not hurt your car and also if the MAF is indeed really faulty ( showing bad values ) it is of course advised to leave the MAF disconnected until you get a replacement. In the worst case scenario you'll get somewhat higher fuel consumption because those default values are pretty conservative.
