Just done 100 mile trip and to be honest, I think I'm sold on keeping the ARL, it was just easy to keep at a reasonable speed but have that little bit to nip past people when needed. Put some Red-Ex in and got 1 big puff of black smoke and none for the rest of the trip, I know its not a permanent fix but the car felt a lot smoother and responsive and just kept pulling, but this could be a placebo effect also. Will see how it starts tomorrow when cold. I know wont solve the compression issue but has made my mind up for sure either this ARL or a new one is the way I will go.
