Jeep

I have a 06 silverado 5.3l with a flowmaster 40 series exhaust and a k&n cool air intake and was considering getting the jet chip upgrade. i was wondering if anyone has experience with these and what you noticed after installing your reprogrammed chip? power gains? torque? etc? i know the company advertises good gains but i want to know from actual users. how much did you all pay? how long did it take?

For the money you spend on it they only produce 5hp per 150hp.use the obd ll and upgrade for free.it takes to long and thats if you know mechanics terms in the way of obd ll most people mess it all up
