  • That's pretty fast.Why is the check engine light on?

  • @timw1959 from the custom tuning.

  • @YoungerPrice I thought so.I have a chip in mine and the light comes on now and then.I own a $50. diagnostic,so I just plug it in under the dash,read and delete code.It works great!

  • @timw1959 i had a chip in my old work truck i have some vids its the tbi350 that had a chip in it didnt feel to much gain then i started tuning myself and its made a night and day difference.dyno tuning is the best by far.
