Getting ready to pull the trigger on a tuner and some bolt-ons for my rig. I've narrowed it down to Livernois and 5 Star Tuning. Both seem to have huge followings, but I don't want to blow my engine or deal with constant check engine lights. Anyone run either of these setups long-term? Pros and cons?

I've had a Livernois tune. It was pretty solid and the power gains were definitely noticeable, but I really didn't like being locked into their proprietary tuning device. It makes it hard to switch things up later if you ever decide you want to try different custom tuners.
