It's possible an injector could be leaking causing the smoke on startup.
That's a possibility. I had that issue with an '86 BMW 535i, so until new injectors arrived, I'd shut off the engine by pulling the fuel pump fuse, which ensured there was no pressure while sitting.

Changed the oil on the Tahoe I bought, sent the sample in to Blackstone. Hoping it’s good. Not sure of the mileage on the oil, monitor said 10% left. Found a few drips of pink stuff on the crossmember under the trans so I torqued the pan bolts. There were some that were pretty loose. Also built the wiring harness for the Pioneer. I went with a Crux interface since the Maestro has increased in price again. Hoping everything works as it should.

you can usually find open box stuff on ebay for more reasonable prices

Installed the Pioneer 3050NEX and Arnott rear shocks. Everything is working correctly after some re-do on a couple things. Crutchfield helped me with getting the amp to turn on and I had a corroded connector where the right rear spoofing resistor plugged in. The old compressor still works! Still have to install the fender liners but I’m waiting a couple days until I’m sure that connector is GTG. Two wins in one day! I did unknowingly unplug that connector for stabilitrack/ traction control that everyone does when replacing the right rear shock. Figured it out instantly thanks to the forum. I had read about it so I knew where to look. So weird that I can’t unplug those things when I’m trying to but somehow that one popped off inadvertently.:p

Whats the consensus on a decent set of rotors and pads for these? I’m not putting Wilwoods on this truck unfortunately; I’m spoiled with them on both my others though. Actually looking to go semi-budget. I have heard Power Stop is fairly decent. Looking at Rock Auto, there’s a ton of choices from cheap to ridiculous. I am considering their semi-coated SC2070 for about $310 shipped or maybe their “geomet” fully coated CRK2070 for about $30 more, not sure if there’s much difference. Not looking to spend much more than that. These prices are for all 4 corners.

I used to use Raybestos E3 pads and their rotors with the 3 tiger paw looking groves on everything and enjoyed them. Great initial bite and lasted forever without dust.

but this hybrid absolutely hated the initial bite thou, it messed with the regen braking badly. the transition was horrible from regen to brake pad. so after searching I found another guy using Warner brakes. looked into them, and they seem they might actually be USA made. ordered some of their QS quiet stop pads up as my truck also had groon from the rear brakes when creeping forward at say a drive thru or something. these have a pad of some kinda damper bonded to the pad backing plate.

so far these are the nicest aftermarket brakes I've driven. they legitimately feel like oem and dead silent at all times. I'm thinking they will be my go to brake recommendation now unless you need something high performance. they offer HD but I don't have any experience with them.

You must mean Quick Stop, I don’t see any Quiet Stop from Wagner. I priced those with their rotors; it came out about the same as Power Stop for the same, coated type. Only thing is they show 2 different sets of pads- solid abutment clip or abutment clip with square hole. Not sure what I’d need without pulling them apart first. The Power Stop is the complete package, pads with rotors so I know they go together.
I see the Raybestos Element 3 for about the same price too, $315 shipped. The pictures don’t show those groovy grooves though. Hmmm.
