[QUOTE="Jam421, post: 16222336, member: 110985"] Made 680rwhp/678tq on my '13 thru 4.10 gears but ratio was slightly reduced in my case by taller MT DR's . Being you drive more than most perhaps the Nittos might be a good option out back. But DR's are a must if you're gonna play. The 680 set up was ARH long tubes, H-Pipe with hi-flo cats, Twin Blade TB, O-Sized Port Matched BPS Plenum, Metco Tensioner for the most belt wrap around a 2.4 upper...stock lower crank pulley. CatBack are Corsa Sports. I later followed Jon Lund's advice with the Power By Hour package. That's the KB 168 Mono Blade, XBA O-Sized Plenum, 148 JLT. Dyno gains were +36hp, no tq change at 716hp/679tq thru the same 4.10's. Peak TQ did raise to 4700rpm which I appreciated. The PBH + Lund 93 Octane Race Tune did cost around $1600 but I sold my old set up to offset half that upgrade cost. Driveability with the KB Monoblade/PBH Package has been exceptional.
