this is the first time i have ever messed with stand alone. havent got off of the part throttle yet, but i can say, that having access to a dynapac at our shop kicks ***. my boss has been using it for a while longer than i, but i can t wait to get the b-sir off of a base map and see what she does with 20 psi. i was kind of scared but it is pretty simple with the dyno and a wide band. just my o.o2 for hondata and dynapac. p.s. ill be learning F.A.S.T. soon too as i am in the market for another G Body to put a 3.8L or 4.1L into.
