I currently have a vmp gen1 with a 2.6 pulley. L&m 77 throttle body with a jlt 127mm cold air intake with a 10% overdrive pulley making 644 to the rear 639 foot pounds. Thinking of buying a gen11r and installing headers to try and vet over 700. What do you guys think? Alot of money for maybe addition 50-70 to the rear.
