I should know the answer to this, but what is the boost with Map 1 on the JB4?

I am still debating if it is even worth getting the stage 2 over the stage 1.

I have the Stage one, and I want MORE, ordering the stage two upgrade kit as soon as she's back from service. (and yes I unistalled it for service) It really only takes about 10 minutes if you have the right tools.

FYI: If you already have the stage one, the stage two is only $150 plus a $20 core charge refunded when you return the stage one control box. IMHO the upgrade is a no brainer.

JB4 Stage 2, Black Grille Surrounds, Black Fender Signal Trim, Body color front / rear reflectors and rear diffuser, DeBadged, 20% LLumar ATR premium tint.
