Sorry to hear Jim!
Most of 'us' have been there - done that... at some point.
Love to remind my brother in law (blown small block) "Lean for a day... rich for life".
That statement, of course, is not totally accurate is it. Rich can kill a motor just as fast as a lean one. The difference might be lean breaks parts - rich just kills the cylinder walls and rings... either way - not good!
I've killed a couple of motors tuning them.... and I've had a couple of motors killed by tuners. Either way - not good!
