As title says,

with covid and the recent c70, been bringing the car up to stage 0 really not to much as full service history, just a set of lower arms and wheel bearing,

so its got a cold air box and cone, boost gauge and just fitted a mbc, left at stock pressure atm, 7-8 psi,

whats the max safe boost levels without a map? 10-12? whats everybody else running at?

thanks guys,

Not an expert on this, but wouldn’t think the boost increase from 7-8 to 10-12 wouldn’t be to bad. My C70 2.5T LPT had a BSR tune that raised it from 193 to 230+ ish. With a boost gauge on it and floored, it would get up to 12-13 psi.

With a few mods, 19T turbo, bigger injectors etc, it’s close to 300 now. This was with a custom tune and dyno.

Just make sure if your going to increase the pressure, do it in baby steps.

hey thanks for your reply,,, i have just installed the mbc, so keeping an eye on boost, I will raise it slowly and see where we end up... thanks for your input I think i will get it chipped and dynoed when the world goes back to normal.
