Do they recommend a lower temp thermostat with the tune you are running?
Not sure. C&L won't reply to any of my inquiries. Normal temp runs around 195.
Changed the plugs today, ping is gone so far but the old plugs weren't very bad. The gap was definitely a little wide but not bad. I will say this... between the fuel filter and the plugs, HOLY COW I didn't realize how bad she needed a tune up! Pulls like a mule now! Hopefully the ping doesn't come back.
