Question for you 90mm users L@@K

Who is or can do speed density tuning in the states? That would be awesome to just ditch the MAF.

It'd be like using an 85mm MAF on a V-6 I guess. Doable? Could this cause improper metering? Perhaps screening would make something of that size more precise...?

Hmmm...this will be post 1000 for me...I wonder if that thing under my username will change...

What did you have to do to make it work (rid of the maf) LOnSLO? Megga tuning or what?

The cruise bucking was all throttle cracker once I pulled that MAF out (+ .9 to the entire table). I suspect my bucking off the line to be the same.
