I would'nt doubt it,especially at night.From what I can tell you need at least 75 degrees outside without a warmer for it to be effective.The more you use it the colder it gets so I'd imagine after alot of back to back runs it will need some heat to bring the pressure back up.I have had my car up to 25 psi with no knock on some short 1/8th mile bursts,but I do need to get a warmer ASAP.I would like a low tank pressure warning system for this,seems to be all that is missing at this point besides enough radar freee open road.
