Sold the old crusty 22s. That put $1k towards the cam swap. Back to OEM 20s. It drives and feels much better with 20s to be honest. I still want another set of 22s though... 

 

At this point it is no longer my daily driver. I got a Chevy Volt because I'm driving a lot for work and it saves me money. So the truck gets to stay super clean and detailed 24/7 and stays inside. I take it out any chance I get when it's not rainy. So much easier to keep it clean that way.. any time I take it out it looks like it just came off the showroom floor.

***side note: My wife didn’t realize her old wheels were on my truck until I told her a month later...??‍♂️ I wonder if I could turbo or supercharge the Yukon without her noticing!? Haha

I could pull that off if I had the cash.[emoji16] My wife isn't that observant. Sent from my Pixel 3 using Tapatalk

Whats the part number on your Xr1? Got any more sound clips?

Part number 40575

1 7/8 long tubes to X and dual 3” pipes  with two Borla 40575 dumped before the axle.

 

Here’s one that I think was a cold start if I remember correctly. I’ll get another driving one uploaded soon too.

Sounds great I just ordered the 400372 multicore which is a 17” oval case, I believe yours are 21”. Hope it’s not too loud with my TSP headers😬. Sounds like these get pretty rowdy on some throttle. Any drone with these?
 

Currently running a 19” Borla ProXs. It sounds pretty good but looking for just a little bit more rasp.

Yes there is a bit of drone, mostly around 2K rpm depending on load, but it’s enjoyable for me, not bad at all. My wife doesn’t like it though. But she drives a Tesla so.. 👍

 

I personally hate too much rasp and it seems like with my setup I’m constantly feathering the throttle to reduce it. Unless It’s WOT — it screams like a drag car then, and it’s all worth it. Haha

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      Have considered installing a DC to DC charger in your camper to replace your isolator?

      Gas fill door

      Common failure.  You need to replace the fuel door housing.   The painted cover transfers over to the new housing.  To remove the old one there is 4 spots where you poke the plastic to release it.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By newdude · Posted

      No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.

      Active Grille Delete

      Hello from Australia Just sharing that there is now a way to delete the active shutters entirely with just a plug in module. Opens up tons of room to light bars etc.

      I have an observation and a question... 1) I watch the voltage closely because I have had to dial in the cut-in/cut-out voltages of the battery separator to my camper.  The "smart" charging drives me nuts.  Anyway, I noticed that when coasting for a while, and especially if lightly using the brakes (though not necessary), the voltage goes up from mid/high-13 volts to mid/high-14 volts.  Then it drops back down after stopping or going again.  Consistently!   The only explanation I can come up with is REGENERATIVE BRAKING!  Well, maybe that's a little bit of an exaggeration, but it's certainly free extra battery charging.   2) Driving on mountain roads I will use L and vary the max gear.  Things straighten out and I end up in L10.  Sometimes I leave it there for a while.  Is there any difference between L10 and D?
