So from what I have been reading everyone says that the JB+/SSTT is safest way to go if your only doing ECU mod.

But, without fuel control, how can this be? Do our cars run rich normally?

All the JB+ does is up your boost without changing fuel control right?

So running lean is not a problem with only 2-3 psi increase in boost?

P.S. this is for daily driver in Socal with fairly warm temps half of the year.
