i'd do 40 Installed. No problems with mine yet but its a car built in 06 and sold as an 07. I assume its ready to blow with my APR sg 1. I dont have a boost gauge. Can you install one of those too? Maybe I can get a few small items together and you could help me out. Need Boost gauge, BSH stg1 pcv, DV, Fuel pump. Then my stage 2+ flash can come. Where are you located?
