The megasquirt is not even close to being plug and play. I ran 25 psi on a 25g turbo with the 8-injector no problem. It was even way too rich because the timing was a bit high so I had to keep the egt's down. $150 to install the megasquirt? Is that like two or three hours of labor? It's gonna take a lot longer than that. Taping in two sensors, you have to remove the thermostat housing and the upper intake to tap them, and then wireing all the sensors from the ecu to the ms. It would be a huge pain in the ass to properly tune both banks, you would be better off with one bank of large injectors.
