So I have not even put any time into figuring this out as a preface to this problem, but I wanted to perhaps get some dialogue going so I save some time. This morning on the way to work, I had this little car next to me that thought he was a hot rod, so I let my adolescence prevail and at the next traffic light hammered my car, I typically turn traction control off, but I didn't this time, nor did I kick my exhaust cutout over, was just horsing around. So I didn't even launch I just waited for him to gun it and hammered the gas, the car started chirping all 4's and the traction control was going all the way to 7k. When I shifted the car stalled, like for a good 1-2 seconds, it didn't sputter just kinda no gas. It eventually kicked back in and was fine. So, keep in mind this is just picking your brains, has anyone else seen this behavior? Is it normal? I can't say I have ever shifted under hard acceleration with the traction control working. My fear is that my bpv isn't closing quick enough, and I don't have the will power to work on my car in 25 deg weather, but it hasn't done this on this tune or turbo since I have had it setup, about 4 months.
