2005 V, Lingenfelter cold air intake, K&N Filter, B&B Exhaust w/ resonators, GSD3's..... Once in a while when I romp it, the engine knocks. Nothing but premium fuel, no romps in high gears with low rpm, 13,500 miles. Any ideas?

Does anyone out there have an oil cooler?

My guess(but keep in mind that I am not an LS6 expert) is that without software, you are running to the limits of the fuel adaption and leaning out. If it were my, I would talk to Rick at Stealth V and send the PCM in for an appropriate tune...bet it goes away. Not to mention that the tune was like half a new car! :cloud9:
