I'm running U4.4 and it's a good unleaded pump replacement without having to re map adds a couple HP but seems to accelerate better all the way through and a good price for the addition of oxygen and tetraethyl lead!!!
If you got the money run the new MR12 best fuel by far but you will have to re-map
there is no substitute for leaded fuel on the race track, I thought the "C" series was just high octane which really will be a waste and won't help make HP might as well run pump for half the price!
