Stall converter
The cam did not make breaking the tires loose any easier, did it? (Taller tires didn't help either.) A higher stall-RpM will strain the transmission, even when you're not towing, even with an ATF cooler upgrade, moreso when you're towing. You want more power UNDER 3000RpM. A higher stall-RpM...- Marky Dissod

Gear ratio
Put 4.10 axle assemblies on your '05 Yukon (likely cheaper than regearing the axles internally). From having tuned many LT1 B- & D-sedans & wagons with 2.56, 2.93, 3.08, & 3.42 (& 3.73 for the more enthusiastic enthusiasts, 4.10 for a few hardcores), 3.42 & 3.73 were the axle gears that made...- Marky Dissod

Your opinion? Parking lights.
If you're asking for an opinion about aesthetics, there is NO accounting for taste; can never be sure 'your' tastes are even really 'yours'. Functionally, amber works better in bad weather, & tires night vision more slowly. Prefer high beams & low beams 4500K-5000K, everything else 4500 or amber-er.- Marky Dissod

Gear selector display dim
cough What does one do if they have a 2002? Looks like Digital Dash Solutions has none for prior to 2003.- Marky Dissod

FW_Z71Burb's 2002 Suburban Z71
And for the DuraMax (& DuraMedium & DuraMini, as well as other turbodiesels), there's "Valvoline Premium Blue Restore", which is pretty tough to find under $75 a gallon, if I'm not mistaken.- Marky Dissod

FW_Z71Burb's 2002 Suburban Z71
Switched to Valvoline Restore & Protect 5w30, winter of 2025. After 3 oil changes with this stuff, my mechanic asked me if I'd bought a new dipstick, had trouble believing it was the same old dipstick. Wish I'd switched winter of '24 when V R&P first debuted. No longer see a point in using any...- Marky Dissod

Tire sizes
I'd go with 265/75R16 (regardless of load rating), I prefer fatter taller tires.- Marky Dissod

Tire sizes
I wouldn't go wider than a 16"x8.5" wheel, but that's me. If they are P265/70R16, NOT LT265/70R16, then 16"x9.0" is a small sacrifice to make for a deeper dish. Just don't carry more than it says on your door, in your bed.- Marky Dissod

Southern California 2003 Silverado SS
An aluminum-head LQ4 is pretty much an LQ9, except with dished pistons & a 9.4:1 scr, vs the LQ9's flat top pistons & a 10.1:1 scr. Interesting fact: After '01, LQ4 LQ9 & LS1 all share the same replacement cam part number: 12561721. Oversimplifying a bit: an LQ9 is basically a cheaper LS1 for...- Marky Dissod

Pop open the glovebox. GU5 = 3.23 GU6 = 3.42 GT4 = 3.73 GT5 = 4.10 4.10'd be best for metro/urban & towing MpGs, as well as the 4L60E's longevity between rebuilds.- Marky Dissod
