Well..like the others...
Nice ride man.
Next...On my Livewire I run the 87 perf tune from Justin as well and I get around 14 mixed on a good day. I can get pretty good if all highway...what MPG's are you getting? The economy tunes are crap..you will get the best MPG increase with your perf tunes..the shift strategies are crud on the MPG tunes and quite sluggish in comparison to their perf brothers.
I have not yet received my tunes from Bill so I cannot give you info that way.
