My question is do you guys think this is too many mods to keep the truck reliable. Sounds like it's got a good amount of fuel mods as well as the airflow to keep up with it. Any opinions would be appreciated because I would be traveling about five hours to pick this truck up. Sorry not super knowledgeable about the newer trucks. I've had a 94 12v for the past 5 years
