i did some logging today . after i let off the throttle my a/f spikes to 21.0 from 2500-1500 on every pull . why would it be doing this . also with partial throttle up to around 4000 rpm it is lean fom 13.0 up to 15.0 at some points .but at wot and anything 4500 up it reads from 11.8 to 12.8 . any ideas on these problems ? im running 30lb injectors and sfmu . hard dark spring with largest disk and bleed valve all the way open .if anything i would be thinkin it was rich but its not .
