just got done tuning a Prelude motor running a built bottom end with a custom turbo kit and custom turbo manifold, stock IM, and open 4 inch downpipe.

the car made 283whp @ 7-8 psi and then 335 @ 12 psi. the tune was conservative (low 11:1 a/f) and timing set conservative as well. overall timing at 12 psi was set to 19*. car could make more power with more timing but ran out of dyno time as well as injector duty cycle (550cc)

gonna drop in a set of 1000cc later on and tune for over 500whp on C16
