Message	I was able to make 443hp and 485tq at 19psi, I would think I could squeeze out 500rwhp @ 22-23 psi. The only time I would turn up the boost that high is for a rare drag racing event. I like the low end spool and power of them tho. Since Chip is not longer building them there probably is not much need for compare and contrast to other turbos.
