I think I'll wait till the intakes and heads are sorted before I look into MAF.
Me personally, am interested in getting as much hp with the bolt-on's already out there without touching things like cam, cpu and bottm end and keeping reasonable economy and drivability!
I read somewhere on the net (not ff) that you can get as much as 300hp with just add on's and running stock cam and bottom end. I think thats pretty impressive.
See what happens
