Right, heres me problem. Just finished off a gallon of 25% byrons, in my hyper 7 .21 3 port, but have blown 2 fasttrax no 4 plugs in that time, any idea why this would happen?
Have a gallon of 25% optifuel race on the way (can't justify the cost per litre of byrons anymore) and an Os no 8 plug on the way. Planning on returning to stock needle settings when it all arrives...
