No not really, just drink more fuel and be underpowered.

Will run like a pile of shit, my mate had a faulty one on his LCR and was awful, so I presume it's the same as not running with one

It's a couple of thin pieces of wire. How is that a restriction?

theres nothing restrictive about a MAF theres no limit to the signal it can send to the ecu, the restriction would be the map/ecu

it wouldnt cause a restriction, my concern would be if its reaching the upper limit, if the airflow is hitting the limit that could cause issues. we often find the need to replace maf sensors for bigger ones so they can flow more, or on NA cars remove them and remap so it runs TPS only

Plenty of boys running BTs with same set up, I'm thinking cold weather, dirty filter, excessive vibration may be the problem, so i'll start off with a new filter and maf
