I completely agree with the first post that the Thundermax ECM and the company behind it are outstanding, responsible, respectful, effective and indeed penultimate products and vendors. But I'm also stoned higher than Sarah Palin's hairdo
.
The Thundermax has promise. Have always conceded that. But it's far (far far far far far [far far far]) from bullet proof. The company's canned maps used to start are too often not accurate. There are almost no tuners around the country to dail them in. The "autotuning" function too often makes poor choices rather than good ones. And may god help you if you need support from the vendor after the fact. Crap shoot at best.
Do you really want to be three days out and some untold hundreds of miles from home with a non-OE ignition system that almost no one besides the vendor knows and have the rest of your trip dependent on a crap shoot?
