off idle to WOT stumble
Quote from Jamesvc15 on August 15, 2018, 6:41 amNew set up dual quads on 5.7 hemi, stock but for a .528 lift comp cam 216@50 duration. vacuum is around 12. The AFR is 14. 59 psi on fuel, I am using the Fitech in line fuel pump .I have about 10 miles on the setup. When I go to WOT off idle it hesitates. I have bumped the Accel pump all the way up to 70 seems better but still not corrected. Ideas?

I typically don't recommend hard throttle or full throttle in the early stages. Many parameters that need to be fine tuned before.
Send me a datalog of 30 second idle. Paste Dropbox or cloud link here. What is your cam setting? I am going to suggest cam 1.
