Any electronic component is capable of being dodgy just at times, eg if it has a dry joint, that will do it.
Any boost induced misfire is very likely to be lack of sparks due to bad coil as this is the hardest time to generate spark due to the cylinder pressure, the higher it is the harder it is to spark for the plug the more voltage it needs.

Thanks... I dont want to hijack this thread.
But mine does missfire with the gear in neutral and accelerating withOUT boost and ofcause with boost. same revs ! EVERTHING is new and adjusted.. besides the ign amp.. thats why I find it interesting. And I have had exactly that thought about the ign amp cause of my experience from work.

Jan< check u have correct voltage at the ignition amp and coil,may just be a wiring fault as these looms are getting old now
Could be something as simple as the amp getting hot and not disipating the heat well??? Has it ever been removed off the alloy heat sink????
If so theres prob no conductive paste on it???
Just a thought

As far as I know it have never been replaced or taken of the coolingplate! I just replaced it in my lunchbrake... hope it helps
) And there wasnt much paste behind the ampfiler.. and that is a good sign so far.
For several ressons I am sure my loom is relativly healthy
I hope
