I wasn't sure if he just sent you a chip or dynoed your car...
Dataloging is also important, you might miss some spike in the AFR reading just looking at the gauge, but I am guessing that for a daily driver that rarely sees full boost for too long, it wouldn't be much of an issue.
The race car is either seeing full boost or no boost, so I am running a pretty righ mixture to keep the engine from blowing up.
What I like with a stand alone system is that you can run without a MAF, but again for a daily driver, a MAF would probably add to the driveability of the car.
What is your estimation of the power output on your car? 300ish? 70 to 100 more than stock? How much boost are you running? 6 - 8 psi?
