First off let me say that i have never had such great wonderful service as a customer, Vivian, Nick and Chris are a good group of people. Immediate response, recieved my tuner in 2 days, and WOW this thing rocks! I, as many guys on here do, read and read about the sct, which one to get, weighed my pros and cons, but let me be the 1,000,000 6.0 guy to say its a must. i got my edge with attitude when i had about 3,000 miles on my truck , and dont get me wrong its a nice convient fun module but this is kind of what id say a "kiddie", or starter programmer. It makes good power but as its famous for a little harsh on the tranny on stage 5. I finally called d.j.'s up and got the xcal3 with the 3 tunes for 425.00 and yea thats a great deal. After installing it which vivian emailed me step by step instructions, this thing is def. worth the hype. Im running looney right now and the shift points are excellent, the smoke is awesome, (even at idle it blows it out revving it up) but most importantly it hauls ***!! If your thinking about getting it as i was lease do yourself a favor and buy iy, your 6.0 will love you 4ever, lol.:icon_ford: Thanks again guys!
