I don't think the Corsa turbos used a different coil, or did they? But then  
again, I was running 15 PSI or more boost...

Then again, remember that GM used a different coil  on Spyders.

Also, recall that in spite of all the modern conjecture, my  Spyder 
still pulled just fine with no misfires through 6000 rpm and I  never 
had any issues regardless of the boost  conditions.

*Something* must have been working  right...
