One more time on the SV-1 . .
We've had it on top of three different size engines, 6 camshafts and raced at altitudes from 3800 feet to 6200 and never touched it on Gasoline. This last season we sent it back and had it converted to alcohol and the only "Tuning" it needed to run a "9 Teen" was fattening up the idle air jet . .
It literally takes the carburetor (and the guess work) out of the tuning picture . .
And we've used it with and without the Biondo SLE, so it doesn't care how you leave the line, or what you do once you have . .
