Yup^^^ also throwing the MAF in the trashcan and going SD is a real gain all the way around.

If tuned right for both, they are equal in power output.

Until you can outflow the MAF, its not as evil as people think

Oh hell I strongly disagree. I agree from a maximum RWHP perspective...but you can SD tune so many more parameters that makes things much smoother...gets you a much wider power band........I didn't say MAF's were evil....but they are restrictive from a fine tuning perspective.

I agree that across load ranges a good sd tune would be better, unless you take a trip from Southern Texas to Denver Colorado. Then I would prefer to have the MAF.

When I did my car, I tuned SD first. Got the VE and everything perfect. Car ran great. Thru the MAF back and it ran like crap. But once I recalibrated the MAF, there was no difference.

I think you'll find that on many other cars that end up doing both. Just takes awhile to get both in line.
