I'm going to assume this is on 93 octane pump gas

With 93 octane pump gas and 20lbs of boost ... No

Keep in mind i have lcon traction bars and a blox drag coilover set up.
Your tuning system should include a two-step. So MSD isn't needed

You don't ADD timing with nitrous. Nitrous increases cylinder pressure substantially. With a 100 shot you need to start RETARDING / TAKING TIMING AWAY
