Just cant seem to get them to open up on a
1st gear burnout..
Maybe not enough load . ?
But the first to 2nd gear shift opens them.
I dont need to roast the tires off the rims , but
surprised I cannot in first gear.
Dont get me wrong . Its hazes tires for 100’
But not John Force style .

As far as cruising and normal accelerating
It is just about as fast as my Hellcat . (Not joking )
Wondering what im missing in the final tune ..

Go pro camera made me prove im running on center at most times .
Thats the coolest thing ive ever watched and streamed
to my smart tv...
if you have '69 carbs then they will open slower than the '70-'71's. pretty sure '69's have a larger kill bleed and a smaller orifice in the center carb that the vacuum hose hooks too. carb list #"s with a -1 after them was supposed to take care of that issue.
