I heard this was the best you can get, so decided to join today. Anyhow, I'm running my Supra under stock twins, BPU'd w/ 50 shots nitrous. I dyno'd 428rwhp @16psi. Now do these #'s sound about right? I've been running like this for a while now with no issues at all, but people keep telling me I should be in the 450's rwhp. Can there be a problem with my motor? I compression tested w/ flying number 165-170 across the entire board. I'm also considering on upping the boost another 2psi. Would this be a big deal?
