Default 50cc or not

Going from Vic mr to perf rpm intake on my 5.3 for more bottom end /midrange power. Do I go back to the 30cc access pump?

I would start there, yes. When it comes to accel pump and shot size always use the smallest shot needed to prevent a bog.

i'd leave it on there and have someone watch behind you to see if you're leaving clouds of black smoke when stepping on it. Otherwise it may still need it, depends on converter and other things.

got everything done. steam vents had to be plugged temporarily till i have some new hardline made. no off idle bog. thought the 50cc might be too big but as of now it seems fine. seems to have alot more bottom end torque. just need to reset the idle mixture with a vacumn gauge to get rid of some of the fuel smell. time to go to the track now.

I have the huge L92 heads. They need alot of fuel off idle since the intake runners are so big they give a week signal. The only thing that got rid of my off idle bog was a 50cc pump and a #40 squirter.
