You absolutely must have proper tuning, period. The ecu WILL NOT COMPENSATE, someone last year tried to say this on a car they had setup and it was bs. We know that you must properly tune it. It also needs to be properly programmed for the injectors. You don't want 14.7:1 eitehr, you want 11.5-12:1.

As noted, you MUST have proper tuning if you want good performance and you'd like to have your engine last longer than a couple of weeks.
