Don't know if SE Turbo give the warranty or not.
The fluid needs to be good and clear. If it is only 2 months old and looks dark, did old fluid get put back in there? Wait, you said cloudy...like frothy? Is it only on the high pressure side? If so, it was not bled (cycled) correctly when it was installed. The pump is probably cavitating or trying to pump a lot of air. It can't built correct pressure with all that air.
See my sig for proper acc bleeding techniques.
The J tool has been unavailable for years...unfortunately.
I would love to get my hands on one but try to find a GM mechanic that will let one go.

fluid
I used some valvoline dot 4 fluid in my new power master and got frothy creamy look in the resevoir. Power flushed and went back to regular fluid and no more froth. I was told the two do not mix!

INCORRECT.
DOT4 and DOT3 will mix. I've done it many times with the Valvoline fluid.
It's DOT5 (usually purple silicone) that won't mix with wither 3 or 4.
Keep in mind that when you convert from #3 fluid, the #4 fluid won't be used to it's maximum benefit until the next time it's flushed. Change it, wait about 6 months and do it again. Big difference. It gives the #3 fluid a chance to get well mixed with the #4 and then it's gone in the next flush.
You frothy fluid is trapped air coming out of the accumulator.
It gets churned up under the pressure the P/M operates at.
You need to cycle it a couple of times to remove the air.
See my sig for proper cycling and bleeding procedures.
But if you are happy with your results, then don't worry.
Power flushed? Did you actually use a pressure bleeding device?
