i have a 2008 chevy colorado 2.9L i-4. stock it sits at 185hp, but with my 33" tires and a prerunner suspension, the lil 4 banger is having a tough time. i regeared the truck with 4.11's and now it needs a tune. im hoping that itll make a huge power difference aswell as get me some better mpg. eventually i wanna throw a turbo in it, so this looks like the best route. anyone got any idea what i can expect out of the V2?
