What did you do to your NNBS GMT900 Tahoe/Yukon Today?

[iamdub]

Took it to get groceries and noted the calculated alcohol content was holding steady at 3%. Will compare to the test tube results and upload the adjusted tune later, possibly tomorrow. But work looks to be building up on me so it might not happen so soon.

I also noted while driving home that my electrical system needs help. Every time the bass hits, even at moderate volume levels, the headlights dim very noticeably. I know my battery is tired. It's been there for 5.25 years and I haven't been so easy on it for the last half of that. So, that will get replaced but I'm also considering an upgraded alternator. Nothing crazy and nothing that'll put undue load on the engine. I wanna keep the RVC functional. I have the DR44 alternator which is rated at 145A. But, it's 222,000+ miles old so it has to be tired as well. I think an extra ~100 amps would be fine.

I'm gonna research, but can y'all suggest a good 250A plug-and-play alternator that will retain the RVC function?

Mine gets twice the MPGs from 100+ as it does from 70-99.

Let us know! I thought someone mentioned 07-20 use same alternator format.. And I thought someone mentioned there being a ~250A factory alt.. (maybe in a 2500 or something)

I just purchased a new factory 160A unit because my old alternator's bearings are going.. Thought I was upgrading, but it looks like my stocker was 160A.. I may not need the extra juice (some lights, air compressor, washer heater and maybe a 2000W power inverter someday..) better too much than not enough!?

I'm still confused how RVC works with dual batteries...

there is a 220amp oem one out there option KW5, just be sure it has the standard pulley and not the clutch pulley (the clutch pulley ones have a nose on the end of the pulley)
this one looks pretty clean presuming it is the one you actually get

Since they’re in parallel, it just sees one big battery.
