Thanks for that. I add the millers in correct ratio. But took your previous advice, and to avoid any potential rear end smoke, (although I never noticed any, anyway), I now only add 25ml of 2 stroke, farther than the 50ml to a full tank. Running really well and tonnes of power when needed, to what I'm used to. Looking forward to the remap on the 22nd. Now I've had the car for nearly a month, I have a good feel for it, so should be in a position to detect the difference after remap. My son and I, have been debating whether we should advise our insurance companies of our remaps. He feels inclined not to bother, but I am more cautious, since any modifications should be advised. He believes that it may just be an excuse to increase premiums, and as he says, it's not as if he has removed an engine, and replaced it with a more powerful one. Any thoughts?
