Some will say yes, I have had K&N on my 05 for 55000 miles, runs great. Have used K&N on everyting I have owned for more years than I care to count. Try some electroni cleaner on MAF see if that helps. Keep us posted as to outcome.

clean off the MAF sensor, prob just go gunk on it from the oil of the filter.

Does it only do it under load? If it does, it could be "turbo bark". There was a dealer reflash fix for that condition. My LLY did it. The reflash fixed it. BTW, I ran a K&N on my LB7 and my LLY for 40k plus. Never had a problem.

i had same problem. in 5th gear at the bottum of gear and then slowly accellerate hard and poof poof and feels like trucks fuel is cut off. took off k&n and went with volant and no problems since. i did bring it to dealer for reflash and that did absolutely nothing except waste a hour of my time.
