I've finally installeda MBC to get rid of the boost-fluctuations and everything works great. Except for one thing.

My chip boosts 1.35 bar. My mbc is put to 1.3-1.4 bar. BUT, after driving on full throttleon 4th and 5th gear a little while, the car chops, probably fuel-cut. No overboost, just stable boost around 1.3-1.4 bar.
This seem to happen ONLY when it's getting a little cooler outside.
So what's the deal? It can't be the boost, because as I said, the chip is set to 1.35 bar and the car peaked @ 1.45 earlier today without any problems.
I also changed my spark plugs to platinum plugs.

Please help! :'(

I've tried to lower the boost, and it get's better, but am I supposed to lower the pressure everyday it gets colder? sounds strange.

Please help!

&lt\\;P&gt\\;A mechanical, the one i showed you.&lt\\;BR&gt\\;I have the bleed-side plugged into the recirculation, where the n75 was. After the MBC is a tee to reach my desired boost (1.3bar) otherwise i will only get maximum 1.1bar&lt\\;BR&gt\\;The plugs are brand new platinum ones, NGK PRF 6Q, i don’t know the gap.&lt\\;BR&gt\\;&lt\\;/P&gt\\;

I noticed that when I'm on fifth gear and a little load (still chilly outside) the boost raises to 1.45bar insted of the set value of 1.35bar.

is it because of the placement of the tee?

If i move the tee to before the MBC, will i get rid of the unwanted increase? will my spool-up be affected?

C'mon, someone had to have this problem before
