u dont need to lower the compression on a 8:6:1

shit....right now im running the stock 10:6:1 on my ITR with boosting 5psi from my charger. i was running a inline-pro 3mm headgasket but i took it out, cuz i dont really need it since im only running 5psi. i will reinstall the headgasket when i run an 8psi pulley and better fuel management.
