I also also put on an AFE Stage 2 cold air intake. I also get that sound, what everyone is calling, the turbo fart. I think that is what it is. If I don't put my foot into it and it shifts throught the gears, no problem. When I do put my foot on the gas, it will go shift and when it does shift I am thinking I'm getting the turbo fart. Is that ok? Thank you all this is again a great site.
