Actually many are getting closer to 550-600 rwhp on the stock bottom end. What you need to watch out for with the boost is the blown HG. I am currently running 15 psi on a mostly stock bottom end, but with arp studs and I am just lifting the heads. I don't have actual numbers, but based on traps and weights I'm in the 450-475 rwhp range. I'll find out later in the week when it finally gets tuned.
what size injector are you running? Good luck with the C&L meter, it's either hit or miss with them. My car ran terrible with the C&L, I switched to a FRPP and the car ran like stock, night and day.
How much boost you running?
