diablo tuners stink
People wonder why such after-market tools cost so much. It is very expensive to provide support for customers who won't even try to read and follow simple instructions, then flame you mercilessly regardless. Will 345Man2 "man up" and return here to amend his rant once he finds how easy it is to use?
I have thought about offering a few products to help the hobby, but the thought of customer support is the main concern. It is hard enough trying to help people on this forum who won't follow thru on simple suggestions and requests like "tell us what year car and engine you have".
