I understand and agree and also learned something. But you do know the 4 port mac solenoids can handle 4-5x the spring rate vs the 3-4x the normal 3 port solenoid (the one aem, hondata, greddy etc all sell). This allows you to run a small spring also. I wouldnt mind looking more into the co2 kits etc. there isnt much info on that msd kit you are running.
