What is necessary with a 90/90 combo? If I get a FAST 90/90 combo, is it necessary to get a 85mm MAF and to get a 85mm lid? If so, how much power is that? Is the NW 90 TB better than the FAST 90 TB? Is there a tuning issue with the 85mm MAF?

If you get a FAST 90/90, it would be highly recommended that you do get a 85mm MAF and Lid. If not, then you might as well go with the FAST 78/78. Not so sure about which of the TB is better, I'm sure they're both the same. Only diff with the NW is the lip before the TB blade is smooth, while the FAST has CNC marks. That shouldn't make any difference. There will be no tuning issue with the 85mm MAF. I have SLP, its a direct bolt on.

I agree Sux2bu, I just bought a 78fast brand new and had 2 do alittle dremeling cause the blade was rubbing on one side.I was hoping to back the screws up and shift the blade,but they are peened and I would have just stripped the head out.You would think during a quality control check they would catch this,rubbing, metal shavings, ahhhh I thinks thats bad,oh well ship it.I hope I dont have a quality issues with the 78mm manifold.
