With colder nights on the stock nissan ecu you will find for the same boost u will have more mass into the engine but roughly the same fuel injected (no temp correction as previously pointed out by hitman and a few others) i.e u will run leaner which fixs the rich tuning nissan put it. For the stock t25g I wouldn’t recommend more then 12psi at any time. That can be your high setting and your low setting can be the stock boost which is around 6-7psi.

With a bigger intercooler the system will flow more air mass again at that boost. Ok for the engine but the compressor will start to reach its flow limits with lower boost settings then you might think.

Hope it helps

good luck with the 180 mate - i just asked the same question, elsewhere. We don't want to blow the suckers up!
