I see from reading on here that alot of people go and are happy with a Nelson Tune. Question is, what are the pros and cons of getting a Nelson tune vs a tuner that will ride in your truck and tune it? How can a Nelson tune get you the most out of your truck by not riding in it and tuning it or having it on a dyno? I don't know what would be best so just asking for opinions and why Thanks for any info.
