Robert Francis, you could have broken off that tab with no worries. I got so much boost now I fried a plug last night in 42 degree weather! Was OK till I hit top end on WOT. then clatter. Shut it right down but knew that firmilure bog that followed.

Fried the #8 plug. Just gave me a good reason to install the Denso 22's I have.
Gonna do a compression check to make sure I didn't burn a valve or piston ring.
