I have a boondocker. I absolutely love it. Fit and finish is great, IMO the boondocker box is the best available now too. The ebc works great for keeping boost at low throttle levels and not over boosting. I think there is a reason all other turbos are compared to boondocker. I raced a cutler up a decent hill, maybe 1/4 mile in ip the other day. He has a 174 3" I have a 162 3". He was at 8.5 lbs I was at 7.4. He had me out of the hole by a sled length, I reeled him in and had about 4 lengths by the top. Btw gearing and clutching were very similar, but he does weigh about 40 lbs more
