my car is not boosting as high or vaccuming correctly

i got flashed to stock and now im worried. At first i was boosting to 10 psi and holding, and now im only boosting to about 8 and holding. I have also noticed that my vaccum is now at 18 or 19 and not 20 anymore. do i have a boostleak?

could be due to temperature. They say you boost slightly less in the cold (because you don't need as much boost).

I was going to say that, too.

But I can't think why your mm/Hg of vacuum would go down.

stock peak is only supposed to be like 8psi. the difference in readings could easily be attributed to a mechanical gauge fault.
