I am convinced with going to the super charger ST.II . It felt crazy when I first took off. I had a permanent smile on my face starting at first gear. The gear shifts were seamless. It almost felt like the Muranos CVT tranny. I felt no lag at all. The sound that the supercharger puts out is like a high pitch whistle when you gun it. I am so happy that Rob gave me a chance to test it out. The Stillen exhaust doesn't have that burbly sound too it like the OEM but it sounds very tamed. I just didn't want to fell the power, I also wanted to see it from a standstill. All I can say is that there is nothing that will touch/compare to the way the FX looks when it takes off like a rocket. WOW! Coming this Feb. My truck will join the elite crew of the supercharged. :twisted: Robs engine sounded like it had nothing while sitting at idle and normal cruising. But, when it was time for fun, there was an ample amount and then some to lend to others who can use it. I am going to have Rob do a few things to my truck in preparation for the supercharger. I am working up to it gradually. If only there was some charity money I can get to put towards the S/C. 8) All I can say is that I am fully impressed. Once you go S/C you never go back. I want to drive it again.
