What's causing fuel imbalance on cylinder banks
Hi guys, maybe someone can help with this issue I'm having. Running the LS fitech 70050 with dual widebands mounted same distance on each bank from header(mid length) collector and I am seeing roughly a 20% correction fuel imbalance between banks.
The drivers side cylinder bank is running richer than the passenger side. Engine is iron LS3, Comp 222/224 dur. .565/.568 lift, 10.2 comp. LS3 intake with 42 lb injectors. 92mm throttle body.
I know before I get comments about this system it was purchased back in Nov. /2017 before Holley came out with their Terminator stuff.
Any ideas what could be the issue........exhaust leak? injector(s), bad o2 sensor? Thanks.
