The main deal is that sometimes this thing seems to have a mind of its own.

I have been looking at Simple Digital Systems (SDS) and MegaSquirt. The factory PCM just has way too many variables that I can not get to with HP Tuners. Have also talked to a lot of guys running the stock PCM and none of us can find a solution to turn the thing past 6400. All of our factory tables end there, and no matter what we try it will just flat line.

I know that Speed Density wont exactly make the car more consistent, but from a tuning perspective will it be easier to deal with than Mass Air?

Also, have you guys dealt with stock PCMs?
