Hey mate. The set up you propse is exactly how my bike is now. PGM splice and GPS splice. Holed airbox lid, good filter. Tyga end cans, factory pipes. Factory jetting.
I had the bike dyno'd and it made mid 50's hp, which is a bit low, but all dynos read different, so im not concerned about the extra couple hp. Its a street bike. AFR was actually richer than i antisipated, so i saw no reason to tinker with the jetting, although it does have a bit of a flat spot at WOT around 5-6k.
Rejetting would definatly improve it, but for my purposes, its fine.
