I finished all of my bolt ons yesterday and loaded the tune today. I data logged it just as Lund said too do. Idled a bit, then two part throttle pulls from 2500-4500rpm’s. Then one WOT from 2500-6500rpm. Then let idle again and stopped logging. About to email the data log to lund. Do they have to “tweek” the tune for it to have any power? It is smooth, but very sluggish with less power than before the mods and tune! Concerns me a bit. Any thoughts? Thanks.
