I understand what you're saying. I disagree about it costing $1200. I only said that MPI was a poor ROI if it only gets you an additional 19 HP. It sounds like you're adjusting your tune for weather conditions which is fine since you like to tinker. I wish that I had the time to do that. Do you have a LSD?I don't want to lose control of my setup. I enjoy tinkering. What happens when you need to dial out some timing? Gotta wait and pay someone to revise your tune. Also, Cobb didn't exist when I went Eurodyne. If you thought MPI had a poor ROI so is throwing $1,200 away to pay $1,200 more to someone so I can....spin more?
