Well it's been over a year since this idea was put out there, but I am chimming in to see if any of use can really get this done. I am definetly wanting to go to one of these classes for diesel tuning. I think if someone who is a tune builder, i.e. Rob Coddens or Brayden Fleece, would show us all the basics and then say these are safe parameters to stay in or "I wouldn't go more than this," could teach the class we would all benefit. I know alot of you are working alot of hours right know, but it would be great to get this going before summer gets here. That way we can all start doing some building before sled pulling and drag racing get here. I hope all are still interested. I also think we need someone to take charge of this and those that want to take the class must commit to it.
