BMS Stage 1 boost setting

[///M_life]

Running BMS Stage 1 piggyback tune. Had it at 3.0 setting over stock. Changed it to 3.5 yesterday. Anyone know what the best setting is to have it at? The 3.5 setting seems to pull harder than 3.0. I only have access to 91 octane and only use shell v power gas. Also live in altitude being in Colorado.

You must have an older version. The newer revision is locked at 4psi over stock..

No mine is brand new. Bought from Burger motor sports in January this year. Default setting is set at +4 when you receive it. If you buy the BMS cable with it you can connect to your laptop and change the boost to whatever you want. I put mine at 3.0 to start but increased to 3.5. I wasnt sure if the +4 was safe to run. Does it make a difference if you have the older one as compared to the newer one with the latest firmware and what boost your able to run? I know on the old threads back in 2014 they said to not go over 3.0.
