Aquamist on BMW 525tds
 

Hallo,

I have purchased an Aquamist S1 system for my 525tds (1993). How much extra boost do i need to get extra power.?
I already have a chip which gives it 350Nm of torque (260 standard) en 170 hp (143 Standard). Last weekend I placed an larger intercooler (530d)
which has a 192cm2 bigger cooling surface. I think originally my boost pressure is 0.8bar. Is it save to make it 1bar.?

Or do i need to go higher to get better performance?

I am pleased to hear from someone with experience on this level.

Thanks in advance.
