Just bought a 09 Chevy Colorado, what performance upgrades would you suggest. I am considering buying exhaust, cold air intake, and either a programmer or chip. What is the best products for the most possible horsepower gains. I want the most bang for my buck but also want the most possible horsepower gains from those three. Is it possible to reach the 350-360 horsepower range from adding those three upgrades? Any help would be appericated. thanks.
