I am wanting to add more power to my 01 1500 4x4 and wanted to know if porting and polishing the tbi and intake would be a good idea. I already have a cai and I’ll be putting on shorty headers and a cat back exhaust as well as a custom tune from Diablo. Later on Im wanting to put in a comp cam but I don’t have the cash now. Anyways…. Is porting and polishing a good or bad idea?
