When i bought my 01 lightning from the dealer last year it came with mods but the dealer didnt know anything about them. Took it to my tuner and from what we could find....6# lower, valve body, idler, drop in k&n filter....wideband a/f gauge boost gauge....not sure if anything else...does the power in the dyno suggest anything else? or do those mods usally make this power.....my tuner said it had a great tune on it so he didnt mess with it.
also what are your thoughts on the results of the dyno?
