Im new to all this tuning. I have a 98 Buick Regal GS that has a custom tune currently from someone else. But I wanna get into tuning it myself. But which kit would be best for me to start out with, the standard or the professional?
I've already read tons of helpful info that's on this site and will continue to do so. I'm just trying to figure out whats best for a beginner like me.
