This may be a dumb question but here it goes anyways. I'm taking my car to get tuned next week and in my crusade to save money and time I wanted to have my boost solenoid setup prior to going. My plan is to have two maps made. One for 20 psi and the other for around 14 psi. So is there a safe way to setup then boost solenoid before hitting the dyno? I've dialed in my AFR's but my timing is only retarded 1 degree per psi.

Setup is
Hondata s300 v1
mac solenoid
Greddy 18G w/TurboSmart adjustable IWG
