Which eddy is it? I have been up/down/left/right with my 800 thunder series. I have found that mine likes Very fat primary and lean secondaries from the base configuration. So you would figure I could lean out the front and fatten the rear so by the same % and it would be fine. NOPE! I wasn’t sure how quick my air door was opening so I hooked a light to it. Snaps open in 1/2 sec and from 2600 rpm to about 3000 rpm. Open fully almost off the line! Friend just was chasing a lean transiton stumble on a duel quad hemi with the eddy afb copy. He couldnt get rid of it. Went fat in the primary and leaned out the sec equal amounts and its gone.
