I dont know if you noticed where i mentioned most of my flames are ignited by a spark plug in my tip. I noticed occasional flames only when my exhaust was super hot and thought it was neat so I put together a flame thrower kit to make sure they happen. Its rice everyone can enjoy!

Interesting.. I've never seen a MAP car pop..

I guess you could get some residual fuel, for a split second, from the time that the ECU sees the manifold pressure change and/or the TPS change.. Especially in an engine with larger injectors.
Heh.. I had a "flame thrower" on my twin turbo Mustang.. Open wastegate dumps, exiting right by the front tires/bumper, always provides for some nice flamage.
