James, After installing my TFI, the pinging remained but much less than before. I tried 87octane fuel but had to move back up to 89 in the warm months. Pulling the trailer up hills caused pinging no matter where I set the pots. I then installed the V&H baggers which increased top end power a little but I still had some pinging. I finished off the power mods by installing Chuckster's dual plate intake which eliminated the crossover tube. I can't make it ping now with 87. Taking the crossover out of the mix definitely cools the intake air. My temp sensor is still located on the intake plate but the air passing over it has to be much cooler.
