Hey guys new here but just wanted to get some input. I have a 97 crew cab 4x4 sice new now 170k miles on it. Totally stock. Transmission just gave out and is being rebuilt. I would like to get more HP out of this truck, as I pull with it everyday. Want to stay safe in regards to the transmission, etc. I've read some about intakes, downpipes, chips, etc. Need some advice. Thanks
