I'm on the fence about tuning my 06 Silverado 1500. I already have Edelbrock shorty headers, k&n cai, flowmaster 40 series cat back and I wanna finish my truck off with a tune. I want more power gains and mpg's. I did some research on tunes from Blackbear Performance and I was impressed but still not convinced. Could someone please post a list of pros and cons for getting a tune?
