Is it fine to refill it with a distilled water only without coolant? I am planning to mix it with coolant if its better but I don't know what is the best coolant and how many do I have to mix I heard 60/40 but I'm not sure.
I am getting a new tune from Ken Bjonnes and hopefully the shifts will be on point. I checked the DA 2 hours after the pass so maybe it was higher than 3600ft. I can't run again because they bounced me everytime because of the safety requirements they want me to put a cage.
