Default jb4+ for M240i. - 04-12-2018, 11:55 PM

ill order the jb+ for the M240i but i have some Questions.

*Can i run ** without CEL or codes?

*What would be the total boost for the M240i? it's already higher boost than
the 340i also safe on pump 93?

*Is it holding 4psi or the boost is additive?

Anyone tried the jb4+?

Jb+ and Jb4 are completely different.

Jb+ has a dial so you can adjust 1-4 psi over stock.

Jb4 is more advanced and has a lot more features with different maps and safeties.

It just depends on how far you want to go with your car.
