I don't have the intake yet, but this weekend I'll likely be installing JB4 with spark plugs+ fuel wires+bluetooth. I am limited to 91 octane (no desire to constantly mix fuel etc and it's all California crap). All I have is a muffler delete. Can I run map 2 right away Terry? Or map 1 until intake, then map 2? Also if I buy a used JB4 off a neighbor for my vehicle... and it comes with bluetooth, do I just need to buy the app for control?
