BMS Stage 1 vs JB4 for N63

Bossman535 · 05-30-2017, 04:59 PM

Can anybody clarify the differences in benefits one can yield between the two? Currently running the bms stage 1 , have the cable so I can adjust boost. It's set at a very mild 2.25lbs boost over stock.

Is there a significant benefit to upgrading to the jb4 ? Not looking to run race gas, but looking to maximize boost on 93 octane.

Current mods: catless downpipes, BB intakes, exhaust.

Thanks!

Jb4 map 2 runs 6psi of boost. Stage 1 maxes out at 3psi and you can bump it to 4psi on race gas. JB4 still makes more power

From what I've read, the BMS Stage 1 is = to the JB4 BETA Map 1
