Flat spot
« on: November 07, 2022, 04:01:33 pm »
I've got a flat spot under load at around 2 to 3k rpm with the stock air box on, but not there with my revo intake. Any ideas ?
I'd be leaving the airbox on instead of the intake if it wasn't there.

Found out the problem, two of the rubber grommets that fit into the airbox were damaged , thus letting un metered air in through the gaps.

Unmetered air would be downstream of the MAF.  The bungs are upstream, so if anything it's more air into the filter box  :smiley:
