Dual quads versus big hammer!!!...

Also one of the things that the engine builder for lwa said was mixing the race fuel in there makes the timing strap and plugs quite hard to read sometimes...
Again putting in another vote for the new AF gauge sensor..
I want to get the tune straightened out and have the correct air fuel ratio and then look for the hesitation. I don't want tune everything way out of whack trying to get rid of the hesitation...
