Default Boost target question - 05-07-2020, 09:52 PM

I posted a question on FB, but since I'm running jb4, I think this is a better venue.

With a jb4, with FW and WG connectors, bms x, ldp and cbe. With this setup, what is the highest psi I should set to not blow the turbos? I'm in Cali, so we don't have 93. So usually running 91 and occasionally 91/e85 mix?

For a non-red sport VR30 and 91 octane fuel - start with Map 1, log, and submit to the forum for review. If all looks good, move up to Map 2 and repeat. There is no golden rule in how much boost psi your car can handle for a given fuel and all of the other variables. Logging is the only way to know how your car is doing and be safe with adding more boost.
