On that note, I'm running a 3.5" with whats in my sig. I've only had to pull minimal timing in some of the upper air mass cells to make it happy.

To do it all over again, I would have went with a 3.6" or maybe even kept the stock pulley.
You also have to remember OP has a GenV, you're still on a GenIII with your ImpSS.

That 3.5" you're running is basically a stock~ ish pulley for a GenV.
