Hi all,

So Ive just installed a CPL CAI intake and am getting a flat spots at about 3k rpm.

Im currently on AFM tune and I think the flow turbulence on the CPL is causing this. I guess that's the reason why the stock airbox has those fins.

Datalog shows spiked to 16 AFR!

My question is how do one tune out these flat spots? I have re calibrated the MAF/AFM voltage vs S.Trim and its still there.

Or do I finally have to go to a MAP tune? I'm dreading the extra work involved with fuel tables.
