So I've got this setup in my car finally. After giving so many of these bluetooth gizmo's as gifts to friends (good tip by the way, it's an inexpensive, but thoughtful gift to anyone you know that is a gearhead, haha) anyway, I finally have one for myself and was wondering a few things.
Boost, I've managed to get it up to around 9psi, what does it top out at in stock tune? What would it top out at in a 4+ tune? I haven't been really able to safely push this to the max due to weather and traffic.
Other than that I am monitoring A/F ratio (seems to be about mid 14's to low 15), engine load and coolant temp. Are there a few other things you guys like to monitor?
