My 2-Stage set up
 

This just in 2x35hp jets. Anybody using a booster fuel pump or a fuel accumulator?
I started with a single stage w/50hp the spark plugs always inspected with good clean
results. Now with the second stage they are appearing a little like it's leaning out.
I have yet to install a fuel pressure gauge to see what the pressure drop might be.
Any thoughts? Click on my images to see the set up.

do u have a wide band my afr's r good with a 100shot

and ur set up looks sick I wanna do a 30 then a 50 I just dont kno how I'd do it cus I dont use a wot switch just a buton

No wide band, My first stage is triggered by a tps switch and the second stage is on a thumb switch, they are totally indepenant of each other.

U prolly should get a wideband
