    Okay i am looking for a good programmer for a 2003 silverado with the 5.3l v8. I plan on adding a volant cold air intake with scoop, gibson performance headers, with flowmaster 40s. What should i do about the cats is it worth the money to get high flow cats? Any advice or tips are welcome, i am not sure about the exhaust so your advice is appriciated.

    Thanks, Dylan

    I have high flow Magnflow cats on my 05 Z-71, 5.3 with JBA short tube headers, Banks CAI, Magnaflow single exhaust and Diablo programmer. The high flow cats compliment the other engine mods. I like the diablo programmer because you can do alot with it, more fine tuning than the others.
