I've done a few megasquirt cars. It is a fairly tunable system, but it is nowhere near the sophistication of FAST, Edelbrock Pro-flow or some of the other established systems. One thing that I don't like about it is that it 'hangs' occasionally, requiring that you disconnect the unit to get it to reboot. This means that the unit always has to be accessible...a real pain in a daily driver. It lives up to the old adage "You get what you pay for." If you want to stick with the factory electronics and want your own control over tuning, then I'd recommend getting SCT's Pro Racer Package. It will give you all the control over your processor that a professional tuner has when he/she is tuning it.
