WOW I just did my first Tren Conversion and it was soooo easy took me about 10 hours but 9 of the hours were waiting for it to set. I bought the DVD, couldnt have made it easier, its step by step are very clear. I also bought a 4G kit witch also made it easy. I'm kicking myself for ever buyin my own tren. If I would have just made it all this time I would have saved soo much $$$$. Feel free to ask if u have any Questions on this....
