Gday, I get 16 PSI out of an 02 model 3Litre, with a standard nissan exhaust, ( is this normal boost ) next a 3" and a front mount intercooler followed by a chip. should go well.
I have a 2.5cr and mine runs about 15-16 so yeah it's normal. I hope. Yeah I'm sure it will go well with the exhaust and chip. What chip are you buying?
