I love my BD dragon. The EBC is awesome. You set your boost and its always at the boost you want. Set 8 lbs and it will stay at 8 lbs all day. I think is a sweet feature. The push to pass is awesome. I hooked it up to a switch so I just flip a switch to get more boost. I have mine set at 8 and then if I think I will need more I hit the switch to go to 10. If I still can't make it, which is rare, I put 12 in the ebc. No guessing on the boost plus it builds boost fast by keeping the waste gate closed until hitting boost number you set. I like the ability to pull my stats off the fuel control box and know my charge temps, rmps, injector duty cycle. Tunnel dump is awesome for never bogging in any condition. Call Justin at Code Red and he will get you hooked up.
Turbo sled can be very reliable but you need to do your homework on what maintenance items need to be taken care of. I look at these sleds like I do an aircraft and you want to change and replace things before you are someone you don't want a failure. They defiantly have more preventative maintenance that needs to be done. If your idea of being a mechanic is its a pain to put oil in it, "and the thing keeps running out of gas," then I would not recommend a turbo kit. If you don't mind tinkering a little bit and enjoy working on a sled a little bit, then they are sweet. If you get a Boondockers kit you can PM or call me and I will tell you things that I have learned with mine.
