MAF over reading - Log included
« on: 16 February 2013, 16:04 »
I installed a Liquid Gauge recently that was showing higher than expected MAF & BHP figures. Have all the usual stage II supporting mods and it is on a standard 180 map.

No fault codes at all, idles perfectly and seems to pull well.

Does anything look odd or may suggest that the MAF could be over reading?

Any one in NW have a spare working MAF or could lend me one for 10 minutes lol
