That's pretty much what I did. Up until it was dyno'd, if someone asked me what power it has, I would say "I dunno, never been dyno'd, but if I had to guess... 180?" I copped a bit of shit for that number but it was the best guess I had...
The car was stock (intercooler ONLY), plus I was young and naive!
Then it got dyno'd at 178.2 runs a higher then factory PSI for some unknown reason... Man that shut some people up
