okay, I read the whole manual for the commander kit, and I have some questions.

For the map sensor, since I look to run at most 16 psi, I've decided on a 2 bar map, good decision?

When I set it up, I do it for tbi correct? I understand the wiring to the injectors, and I think you can tune it to accept a group fire type deal. My only question is does it fire the front two, middle two, then back two? Like whats the order of firing?

When using a 5.3 chevy TB, is a TPS sensor already in it?

And what about an IAC valve for the a/c? Is it in the TB, or no?

Also Tom, how much would your machinist charge to make my intake with bungs, and fuel rail, if I send him an offy 4 barrel intake?

Thanks guys
