Running lean

[camarofan1974]

i have a 98 gtp mods:3.4, pcm, cai, downpipe,cat resonator and u-bend delete, 3in exhaust into chambered mufflers, ported exhaust manifolds,ported tb lim and s/c, msd coil packs wires, 104 plugs , t-stat, a/c delete, and poly motor mounts. ive checked for vaccume leaks- none ,maf-fine...could i be just flowin too much air and would injectors help? if so what size?

Re: Running lean in one bank?

No...you don't need injectors, you need a tune. When you ported your throttle body it skewed your MAF readings bad.
