The problem started a few days ago, it ran fine last week, in a stock tune, the truck loses power and boost when put the throttle we were losing speed and boost and then I looked back, and once, there was a little puff of white smoke, I hope it is no the motor. It was running fine yesterday. Also, it kind of smelled, don't know what but it smelled, all the temps were in check, but the boost fell when you gased it. So if anyone can help, that would be great. Also, it isn't shaking badly or anything like that. Is it the injectors? We'll get it to PPE on tuesday and have them check it out, see what's the problem, but any input would be nice
