well as the title says...I am wondering if I need a turbo timer for my turbo kit...or is that overkill? if I jst spend about a min or so everytime I stop...staying out of boost...is that enough...or would a turbo timer be a good addition...and about turbo timers..will it keep my car on..and I can just walk away? or do I have to stay in my car for the time it calculates for cool-down?
