Why should I buy stuff from you?

I have done this for about ten years

I’ve spent an inordinate amount of time in my own car and others figuring out what all the knobs and switches do in your stock engine management system.

Proven and tested

I don’t sell chips that I haven’t personally tested.

Your car doesn’t turn into a science project

Your tune could always be a little better. Maybe you could just keep the interior disassembled so it’s easier to mess with. It’s not so bad if the laptop has to stay plugged in to start the car, right?
