That's on pump gas and meth. I haven't gotten it tuned on race gas yet.
I was at that power level on pump 18@ psi. The turbo really comes alive with higher boost and race fuel helps. My final pump map at 21 psi was 400whp. Built block. Some cars react different to the fuel and so on. I bet the tuner wanted a safe tune for you. But I'm only assuming that.
