Just need some of your specialist performance expertise. I am currently running a 9-3 LPT with the follwing:

Speedparts Stage 1
Speedparts Induction Kit and heatsheild
MBC
Eibach springs and dampers

I have just installed a boost gauge. When flooring it in third, boost seems to be peaking at 1.3 bar and then settling at around 1 bar. Do you think this is ok for day to day use, or should I wind the MBC out a little for the longevity of my engine? All thoughts are much appreciated.

Thats as far as you can probably go..

My mbc on high (dual stage ) was peaking around 1.35 bar and occasionally bumping the overboost
on low (1.1) it would never touch the overboost

If you go farther I would check your a/f ratio just in caser you are getting to the edge of your fuel system...

Cheers for the prompt advice ylee! I wasn't looking to wind it up further, just checking that this level was sustainable without the engine going bang! I'm very very happy with the performance at this level of boost!
