Does anyone know if the L8T can advance timing i.e., could it advance it enough to take advantage of 93 octane while towing on a hot day, not to pull timing due to pinging? Per AI. No idea if it is true. Yes, a GM truck with the 6.6L L8T V8 engine can benefit from 93 octane, though the gains depend on how you use the truck. [1, 2, 3, 4, 5] Because the L8T features advanced engine management and variable valve timing, its computer will automatically advance the ignition timing when it detects higher-octane fuel. The primary benefits of 93 octane in an L8T include: [1] Improved Towing Performance: When pulling heavy loads or driving up steep grades, your engine runs hotter and is more prone to engine knock. The ECM will pull timing to protect the engine on lower-octane gas, whereas 93 octane allows the engine to maintain full power under stress. [1, 2, 3, 4] Better Throttle Response: You may notice a sharper throttle feel and slightly better low-end torque. [1, 2] Maximum Output for Tuners: If you add an aftermarket handheld programmer, the engine can be fully optimized to take advantage of 93 octane, yielding noticeable horsepower and torque gains over the factory tune. [1, 2, 3] If you are just driving unloaded without a trailer, the standard 87 octane recommended by GM is perfectly sufficient and cost-effective. However, if you are regularly towing, hauling, or looking for peak performance, 93 octane is highly beneficial. [1, 2] If you want to optimize your truck's performance, tell me: Are you planning on adding any aftermarket tuners or programmers? How often do you use the truck for heavy towing or hauling? I can help you decide whether the premium fuel upgrade is worth the cost for your specific driving habits.

Banks diff cover added. For those who have not greased their 9 zerks in your frontend, do it. Mine were bone dry.

Mine goes on tomorrow.

Sold them.

Catch can added last night. Will add pics later.

I am running the Bridgestone Dueler A/T Ascent and love them.

After putting 2500 miles on these tires, not loaded and towing. I can say they are awesome. Heavy rain, NP 85mph quiet, boat ramps NP towing the race car through wet grass NP. Highly recommend.

Has anyone found a Cat Back Exhaust that does not drone when towing?

Thank you all.

Love mine also!

Do you have a pic of the exhaust tip?

Where do you pick up the rubber washer that is on the oil drain bolt? Went to the dealer today and was told they are on back order? Advance Auto sells the bolt with the siclone washer on it. Picked up 2 so that I would have extra.

Wet handling and boat ramp slipping. The factory Goodyear was horrible. Just pulled the boat out for the day, and the Bridgestone was night and day better in every way. I had the AT3W on the Tundra, and they were even worse in the rain while towing. We also have a vacation home that will be our retirement home in the mountains, with a 1/2-mile dirt driveway that can be anything from dirt to mud to snow and ice.

Which catch can is that?

It features a unique sawtooth tread design, 3D sipes, and is 3-Peak Mountain Snowflake (3PMSF) certified for severe snow service.

Same first time for me hearing this also.

Not one of the 4 tires was over 12 on the Road Force machine.
