I put a heavy load on my truck the other night and noticed it had hardly any power to go up hills. It has a banks Sidewinder turbo on it already and I never hear it wind up or anything and I took of air hose and saw it spin and think bearings have gone out and wont let it go faster. so I plugged the weight of my load and truck and speed into one of these horse power calculators on the internet and compared it with stock specs and I am only getting stock horsepower. Basically will the time and effort pay off with getting a new turbo.
