Looking @ ECU upgrades but wonderin' what manufacturer to go with. Any thoughts???

 

well m2/pettit is fine and cheaper than others but you can't really tune it and it doesn't help you with monitoring the car.
haltech seems to be the best but geared toward more hard core guys, also its a lot to install.
pfs is ok, i don't know too much about it.
apexi power fc is nice for ease of install and tunability. plus it lets you monitor just about whatever you want.
