Congratulations.
I tuned on my truck for about six months then ImportThis's truck for a couple months before I got a good knowledge. Then started tuning tire and gear changes for guys around town. It has progressed from there for me to tuning head and cam cars. No FI yet still find it very intimidation on HPT.(means I need to read more). However, I will let you in on a secret about HPT if you read on there forum and think it looks like they are speaking Greek. It is not just you who thinks this. When I first started I thought everything was Greek now only a small part of it looks that way.
