sweet, thanks. What is u4.5 fuel?

And still no word on the timing?

 

I use a vortex ing. module to control my timing and u4.5 is the new u4 fuel it replaces the old stuff which was a nasty mess to clean up if you left it in your tank.its only 99oct but runs better then any race gas i have run before.

 

how much timing are you taking out for say a 20 shot?

 

.5 to 1 retarded im very conservative on my timing
