Ok my truck is used to tow it is used to tow heavy truck is 9000 lbs its self add dump trailer tips scale little over 16000 lbs now add 8000 lbs rock and yea its heavy. now i have 60 hp injectors in it and the rest is stock and works good. now its turbo time and want to put a jake brake in it and increase hp a little, not to pull sleds, just give me a little more power to get her going a little faster on coming out on the road, dont mine replacing the manifold had to put a chepper one on when stock one cracked. what setup do any of you use or suggest.
