he has a 05 3500 single wheel 4x4 w/ crazy larry , 4 in exhaust , afe intake , and zex nitrous (not installed yet) . he is want to upgrade to a bigger turbo , maybe injectors , intercooler , high ram , and maybe water meth . what about stacking w/ the crazy larry ? he is wanting it fast but yet still drivable . the truck is lifted with 35s and is not used for towing . looking for any input on what is working and places or people to buy from . i will be doing all the work myself . one more thing does he need studs w/ just the nitrous ? thanks
