Watching the gauges for charge air temp, ambient, and IAT seem to point to an adequately sized intercooler. I hope this holds up as the weather gets warmer, too. FWIW, we've had a couple days around 80 deg F, and there isn't any evidence of heat soaking the IC. This might be the first stock turbo car I've ever owned that enjoys this! If you watch the various dyno videos, you'll see very consistent runs. The guys at Edmund's also pointed this out. Almost every car faces a heat issue on the dyno, so this is very encouraging. It bodes well for track days in the summer! That aside, I could see a bigger intercooler, but it's not a priority for me now. For those that have it, do you have instrumented changes for before and after?
