Nah only joking.
I have tried all except the vortex.
I have a A14 running 10.6:1 comp. I can run normal premium but there is a noticable differance when i use optimax & a bigger differanc when i use synergy or BP ultimate.
What type of plugs do you guys use. I have never had any foweling probs but i use iridium plugs.
I have started using a octain boost wich you race guys might no about that uses real led. Alot of guys racing historic classes use it. I cant think of the name right now but i will let you no.
