Re: weak points on engine
Bolt on's mean nothing with these trucks if the truck isn't running right to begin with or if it's out of tune. I've seen trucks with the hardware to run 11's all day long run 13's lol because of the tune.
With that said, do what others have mentioned and have the truck gone over with a datalogger like datamaster. Post up on this forum to see who's close to you that has datamaster and can spend two hours of there life to help you save thousands of dollars and many hours of your life because these trucks don't handle abuse like turbo regals can.
Good luck
