Programming the ecm.

Synthetics front to back.
good points - checking into a lot of that.

my dream project would be to grind a cam with a atkinson style of profile (huge intake duration, short exh duration) but i'd only do this if I milled the head for increased compression ratio since atkinson motors are half again as much as a typical gas icm's. But since I'd be dealing with a engine tuning learning curve from hell, i might not attempt this any time soon.

so, as a cheaper alternative, there is a factory mustang SVO turbo cam that adds a little lift and duration to what i already have so I might give that a go first with an adjustable cam gear.

the factory cast manifold is a 4-2-1 design, and no aftermarket company makes a CARB compliant header for this application (I'm in smog nazi california)

re the ecu upgrades, i need to polish up on my eec tuning skills. Currently that is way over my head, so i'll probably resort to a wide band o2 sensor and gauge, and tweak the sensors to give me the kind of numbers i seek.

i have changed out the oil to a 5w30 mobil 1 from 10w30 dino, and might look to do something similar in the diff, but i don't see any benefit in messing with the recommended atf, other than a trans cooler.
