I have been using my 04 Blazer 2dr 2wd 4.3L to practice tuning with HP tuners. Since I started I went from a 18.1 to a 16.2 in the 1/4 mile not bad for a butt Dino and not knowing what I'm really doing sometimes. The 4.3L is stock except for K&N cold air intake.

Chevrolet Blazer Ls 4.3L bracket racing solo pass.

Last race for bracket racing and I believe this guy sandbag me. He taps his brakes right at the 1/4 mile marker. I am a stock 4.3 l 16.7 in the 1/4 Mile there was no need for that just to win.
It was 108? and track temperature was about 151?
