Oh, and not even 5,000 mles on my truck yet and my valves already look like shit.  I've changed the oil 3 times.

So my new manifold showed up today, (in a Roush Racing box ) so I got the installed finished.  Pretty straight forward, here's a bunch of pictures.       Intake

Ordered this truck from the dealer I work at towards the end of September and it came in on Monday. 2017 RC Z71. 5.3 flex fuel engine. Not sure what I plan to do with it yet. I want to lower it

These trucks are direct injected, they don't get the benefit of the atomized fuel cleaning the valves as it enters the cylinders. A good pcv catch can is almost a necessity.

I did get my New Handheld  tuner and base tune in today, so at least I'll be able to drive to Maine for my dyno tune.

Blower. The seal is and o ring that fits in a grove on the manifold. It was a pain in the ass to seat:

Pullies

And done. I added the Gates HD belt, it came with a regular Gates belt.

The SLP intake it came with. I'd rather use the stock airbox, but I'll have to rig something up later for that.

It's running.I dont trust the tune but at least I can drive it to the tuner. I'm showing 10 psi on my boost gauge at wide open throttle. 

 

Also, I think there's an issue with the T harness for the IAT relocation because it's reading - 40 degrees, so it's open somewhere. So right now I'm reading IAT off the MAF still.

Why don’t you trust the tune? It’s my understanding that the tune included with the kit was developed by SLP (ROUSH Performance).

The SLP tune doesn't work for a '17, so the company I bought the charger from told me they would get me a custom tune for free since they told me one was included before I bought it. 

 

So I've been working with the tuner for the last couple days trying to get it right. 6 tunes later it's running, but he said he couldn't get it any closer without a wideband A/F gauge installed. So that's why I don't trust it, i figured he would be able to see everything he needed with the data logs, I sent.

Hopefully you can get the tune dialed in perfect to your liking.

 

Does it run like a bat out of hell now? :)

It definitely has way more power, I haven't gotten on it too many times though because I don't trust the tune.

So today I replaced my spark plugs with NGK 5107 plugs. These are the plugs that come in the Whipple supercharger kit and were recommended by my tuner. He said to gap them to 0.022"-0.024". 

 

He also said to remove the active grille shutter and he would delete the codes for it. So I did that today. The ambient air temp sensor for the radio temp is on the bottom of the shutter, but the mounting hole for the '14-'16 trucks is still on the' 17+ trucks, so I modified the harness and installed the sensor in the older Truck location. 

 

Here's some pics in case anyone wants to delete these too. 

 

The red circle is the new location of the sensor, and the green circle is the connector for the harness. I forgot to take a before pic so I stole a pic from @BlackBear88 since that was the first one I found in a search. LOL

Original temp sensor location.  You can actually see the new location to move it to in this pic also.

2017 and newer trucks and suvs have that shutter on the front. It closes at high speeds to reduce drag. I think it also closes when it's cold to help heat up the coolant faster too. 

 

Deleting it will make sure I'm always getting air flow to the heat exchanger.

      2018 Silverado Console USB Port Not Working

      By Tbhats2130 · Posted

      My centre console USB ports haven’t been working and the one in the glovebox is starting to act up. When I plug my phone into the cord the radio will go black and stop playing, and the CarPlay is inconsistent.   I checked the fuses and they were fine. I changed the USB port out and still nothing. Hoping for some advice on what I should be looking at.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      The truck is a 1995 Chevrolet S10 Blazer, 4.3 VIN "W" engine. :cracks knuckles:   On a whim - because I needed a headache - this truck was for sale so I stopped to take a look. Doesn't run. Well, it does, but barely. Long crank, choppy idle, bad misfire(s), it REEKS of fuel. I can DO this..I'm thinking. Diamond in the rough. One owner until last year. A young guy is selling it, he bought it 6 months ago. It stranded him more than once, he's got a newborn. It was in the shop 10 days ago and he "thinks" they said it needs a new fuel injection system. He can't put any more money into it, needs it gone. I was thinking of upgrading my Macbook, which is a total want, not a need. For less than the price of a new laptop I can have fun for months tinkering on this truck and enjoying it. I'm taking this truck home. The guy was beyond thrilled, his wife was there, she thanked me profusely, I could tell they were hurting. They seemed like good people in a bind.   Some parts, a wash, maybe a set of tires, and I can have a few months of fun and then turn it for beer money (or the next project).   Sure enough, there's a work order from a shop last week in the INCHES of paperwork on this truck dating back to when the first owner bought it. They put a new distributor in it, fuel injection work describes basically opening the plenum and putting it back together. He said he couldn't afford any more work so he had them button it up and that's when he put it up for sale.   I'm not well versed in 4.3. I did discover 1995 uses the 1992-1995 SCPI "Spider" injector which is riddled with issues from splitting lines, clogged or cracked poppet valves and plastic spider legs that crumble over time. Cool. I'll just order me a ne---. Oh, the auto parts store doesn't have it? Rock Auto doesn't have it. eBay? $$$$$$ for used. These are UNAVAILABLE period end of story unless you know "a guy" who's still got one in a box somewhere.   Can't upgrade to the '96-'04 injector, it's a different plenum, wiring/pinout and sensor config.   There are a few kinda "know a guy" -guy rebuild services for these injectors out there for about $350. Okay, Okay... I'd like to know if anyone has used them? Anyone got a lead on these crappy 92-95 spiders?   I also don't want to send MY spider to Narnia and back without knowing if that's truly the problem. I guess I'll need to pull apart the plenum and do some digging.   I was also thrown for a loop. This 1995 model year truck has an OBD-II connector. The interface is decidedly not OBD-II. I can read and reset trouble codes and view live data, but there's not a lot of data. Like misfire count and on what cylinder, that's not there. It's OBD-1.5.   Nothing is ever easy. Now it makes sense why this guy wanted to disappear this thing for cheap. I'm guessing the shop told him the injector is toast, the part is unobtainable and they're not going to sort sending the thing to a rando offering rebuild service on craigslist, and the kid likely can't be without a working car for 3 weeks even if they'd facilitate that.   Experience with these early SCPI's? Stories? Things to check? Sympathy? (..Nah...)   This can sit until I sort it. But I haven't had a problem with a vehicle I couldn't easily solve in a long time.

      I have four that read by the dash 8 to 10% better than miles/pump calculations and I have one that is spot on.
