I've had this issue for a long time now. I haven't been to the track for over two years until tonight and it is still having the same problem. What is weird is that it did the same thing a few years back when I had a totally different engine/tranny/suspension in the same car. Even the ECU was different in that combo. Anyway, this is what is happening:
Engine first started bogging directly after shift to fourth. Occasionally hear pinging to while it is bogging. The bog will vary from a half second to maybe two seconds long then it will run normal. I did quite a few runs and noticed it doing the same type of bogging in different gears each time. Once it did it after 2nd and 4th shift, then another run it bogged at the line and also after 3rd shift. It was worse tonight than I remember it before. I'm not sure what the deal is. I was thinking ignition but if it was doing it years back when I had a stroker with full MSD ignition and Tweecer etc. I dunno what the deal is now.
I thought that my D/S out of balance was throwing it off but I had it rebalanced last year. It sure feels like ignition to me but maybe it is a fuel issue? I do not notice any issues on the street, just at the track at WOT right after shifting.
