I have been a gear head since before I could drive, getting a drivers license just cemented it. I went on to become a GM dealership mechanic at 2 local dealers. When a career change decision lead me to building aircraft engines, I found I missed having all the scan tools and being on the cutting edge of new car technology.
I purchased some tuning software and attended some training courses including EFI University for performance tuning.
This has filled the gap for me and I enjoy being able to make factory fuel injection systems work in ways they were not original designed or intended for.
