I don't particularly have a problem...I just have misfires sometimes but it's very rare. I use 95 ron(eur) fuel and a lot of methanol because I don't have E85. I wanted to improve my lighting, just to make it perfect.Just curious. are you seeing anything in particular in your logs or car performance that finally made you decide you wanted to get them? I’ve gone back-and-forth on whether or not to get them.
