Edit: Nevermind, I called the company and it looks like the price for them to rebuild is very reasonable in comparison to buying a new one again. Realized my no-start culprit this whole time was the msd digital 6 box. Buddy of mine returned things back to the stock setup and she fired back up.

Now, should I have this one rebuilt by MSD or buy a new one? Why/why not?

It's an LT1 with a T-trim, obd1 pcm. It ran great up until now, so I'd like to keep this model box so I don't stray away from original settings and can just plug and play.

Thank you
