Heya Stratosaurus,
Mr. Ito's outstanding TU-22M3 file tu22m3bc.zip doesn't come with afterburner effects. This means that you will have to add your own.
I use the excellent Military Effects Pack v1.2 by Toshikazu-Shimizu (Water-Toshi) available here:
http://ww71.tiki.ne.jp/~water-t/dl/milpac012.zipThis package comes with everything that you need to add military effects to any aircraft including detailed instructions.
There is also another effect that I have a lot of fun with called Sonic Boom for Fighters available here at SimV:
http://www.simviation.com/fs2002misc10.htmAlthough written for FS 2002 it will still work with no problems in FS 2004.
If you have any questions concerning installation just IM me here at SimV and I'll be happy to help.
