boost problems
 

I have really strange boost problem, missing about 0.5bar. Currently im getting only around 0.85bar, should be like 1.35-1.4bar. I have double checked about everything, no leaks or nothing.

Some things i noticed:
- injectors open max 48% (sard 650cc)
- dump piston is open on idle (forge dual-piston dump)
- when accerlating -> ~4000rpm, gear up -> i can hear like push back sound from turbo (td0516g), over 5000rpm and there is only normal dump sound
- lazy when accerlating
