Made a little video this morning. Wanted to see how bad the vibration was on my truck at 100+ and to get a top end video. The only vibrations I noticed on my truck was right around 110-114. After that the truck smoothed out. Truck seemed to pull well up till 120 and then the last 10mph was the struggle.

I'm guessing your truck is NOT stock. :crackup:

It is not lol. K&N drop in filter, custom cat-back with a Venom 250 muffler, and a Klug Performance e85 tune.

Cool video. I used to do this with my 88 Volvo 740.. took a bit longer to max out around 114mph ;). Seeing the "4 wheel drive shift in progress" notificaiton made me physically uncomfortable. Assuming it was automatically shifting OUT of 4x4, but under a lot of stress. Glad you're enjoying your ride!

When I do a 1/4 mile pass or a tuning pull with my truck I normally leave it in 4wd but i didn't feel comfortable leaving it in 4hi to that high of a mph. I would not recommend switching like that on a regular basis that is for sure.

Do you know what your shift points are set to? RPM seemed pretty high.

I have them set to 6400rpm. Started at 6000, then went to 6300, and ended at 6400. 6400 had the best 1/8 and 1/4 mile times out of the 3 different shift points.

Dude buys a 5400 lb truck with the 'off road' package and not the biggest engine, and is worried about 1/8 mile and 1/4 mile performance. And then proceeds to do transfer case shifts at wide open throttle.

 

No wonder the General bends over backwards trying to deny warranty claims!

Not many people do this to their trucks.

I'd love to have a Camaro SS but can't afford the extra payment of a second vehicle. A Camaro SS can't go through 2 feet of snow and do things I need the truck to do. I love my truck it can perform well at the track, go through mud and snow, pull a trailer, and haul stuff in the bed. That is why I bought a truck because how versatile it is.There is a reason they make aftermarket performance mods for trucks because there are other people who are interested in performance out of there trucks as well. If you read my comment above about shifting out of 4wd I said I DO NOT RECOMMEND shifting out of 4wd like I did. Then again I am the same person if I had an extra 20,000 to spend I would get a stall, cam, heads and an Armageddon twin turbo kit for my 5400 lb off road truck. To each there own.

Yeah they do

 

Anybody who thinks it's horrible for the vehicle does not understand how the transfer case functions.

And I was happy tonight just hearing the mild Flowmaster exhaust during moderate acceleration from 0-60 while running errands. To each his own. Would love to watch the Gorske in a 1/4 mile run though............

If you have the means to repair any potential "catastrophic" part failures, I say mod to your hearts content and as always, more power is always better.

 

I'm lucky enough to have a heavily modified 2011 Camaro SS/RS, all done by me, and I'm always looking for mod's I can do to my 2017 Silverado. Some of us have the mod "gene" I believe, albeit a habit that doesn't always make for a large savings account[emoji51]. You only live once brother, do it to it.

    • Monthly payment is only part of the equation. With today's prices and interest rates, I'd look at the total monthly cost: payment, insurance, registration, fuel, maintenance, and expected repairs. A vehicle that fits comfortably into your budget is usually the better choice than stretching for a higher trim. I've also kept my vehicles longer over the past few years. New cars have gotten expensive enough that driving one for 10+ years, while staying on top of maintenance, often ends up being the most cost-effective approach.
    • 10 Ford and Chevy engines proven to reach 300,000 miles   You may note a common 3K OCI on this list of gas motors. I skipped over the diesels. Dh'O. 
    • Thanks newdude!  By the time manual selection is needed, I'm probably too much of a control-freak to depend on the transmission sensing braking to activate automatic downshifting.  I would be anticipating the situation and already be manually downshifting.   This truck replaced a 2004.5 LLY diesel with the Allison 5-speed.  Putting it in T/H made noticeable differences (when the torque converter locked, upshift points, downshift behavior).  On this 2024 gasser with the 10L1000 I haven't been able to detect much, if any, difference.  Ok, I can never tell now when the torque converter locks up.  But I also don't notice differences in shifting.  For downhills, I've probably already manually downshifted by then anyway.  Since it's also more awkward (than the 2004.5) to engage/disengage I don't even bother.  Or maybe it doesn't really matter with just a 3k lb. camper in the bed?   Thanks also for the list of reasons the charging system might select various voltages.  However, what I am seeing doesn't fall into any of those categories.  It very definitely, and very consistently, rises after coasting/braking.  Maybe not immediately, but not very long after coasting/braking.  Very consistently drops voltage when no longer coasting/braking.  It might also be interacting with the camper battery charging (I might disconnect the camper and see if it changes the charging behavior).  I also need to recheck turning on headlights for when I want to force it to charge the camper.   Another JR, in June I converted the camper to LiFePO4.  Since it's not a good idea to try to charge lithiums directly using truck, I installed a Victron Orion XS DC-DC charger (which BTW is AMAZING!!).  Being cheap, I only had to buy that one item (besides the battery, of course) to do the conversion.  The camper OEM 120v battery charger (only 19 years old and works perfectly) and the truck feed the input to the DC-DC charger (not at the same time).  But I didn't want the camper charger feeding back to the truck so I kept the old separator.  I considered replacing the separator with a 30amp diode but that means more work and might add another 1/2 volt drop.  One thing that surprised me was the voltage drop over the long 10awg wire run, so I can only charge smoothly at 8 amps (because the DC-DC charger is completely configurable).  Another reason I don't want an added voltage drop with the diode.  I might also be a little lazy but all this work is being done under the sink with a small cabinet opening.    
    • apparently CA smog is (or at least was)  checking that the vehicle is using the oem and/or a ca smog approved tune, so I expect you'll fail inspection doing it.
    • yes, leaking exhaust will mess up o2 sensor readings, which in turn messes up fuel trims.
