That sounds terrible, Jim. Are you referring to Eurocharged, Vtech Georgia or MSS? Just so we are not spreading false info here or accusing someone who might have had nothing to do with it? What happened to the transmissions? I would have been very very upset. Plus I hate a business that doesn't stand behind their products. If you mess up, admit to it, make it right and do better the next time. Of course, most tuning companies will tell you "at your own risk". It could be total coincidence if someone gets a tune and a day later parts break but if it happens to multiple people and in the same way, that is facts!
