Balancing fuel injectors

[rudyann]

In anticipation of investing in GAMI's, I performed the lean test on my NA Lance and discovered that the only cylinder out of whack is number 2. It is 1.4 gph leaner than the rest. I switched number 1 and 2 injectors at annual and the lean cylinder remained number 2. It seems a shame to spend 1 AMU when I really just need to enrich number 2. Any ideas?

Thanks in advance.
