I have to retract my opinion or modify it. My initial impression was on a few wot passes. I took the blown caddie to work today. Under general driving conditions is where this really shines. It's very clear how rolling into it or just moving with traffic accelerating etc the sc makes a night / day difference. My initial impression is Definately jaded vs having spent about 2 hours behind the wheel now .

 

It's a mod at the top of my list for my 14. Just ordered autocal from blackbear to ride me over until I get a maggie on my truck .

 

Also as a correction our caddie has the tsv 2600 on it not the 1900 I thought it was.

Any FI LS will givver good, you're just used to feeling that flat torque line of ur diesel...I've been in a couple quick gassers it's def a diff feeling. The power is all up top and diesel is all down low...

That's exactly why I want a diesel now. Never had a need for one, and a gasser will do everything I need it to, but I miss the days when a gas V8 had most of its torque on the low end.

I agree. It is criminal that the gasser V-8's haven't been developed to generate peak torque lower in the RPM band. Makes one wonder what the folks at the OEM's are smoking to have peak torque at 4200 RPM. Like anyone pulls their boat, camper, trailer putting their engine RPM's on the ceiling. Now if they would turbo or blow them properly from the factory, then we could have that power lower in the RPM band. I have wondered for a few years now why they still use ancient ideas like naturally aspirated engines. Surprised the vehicles don't come with only AM radios like they did back in the day.

With an older NA motor the "problem" was that they had all the torque down low. Because that meant they had all the fuel economy nowhere, lol. I don't care about it that much, so I would love to have a supercharger.

I wish a blower was a GM factory option when ordering or at least a supported mod like the TRD Supercharger kits were for the Tundra. After driving the blown caddie vs my 14 5.3 liter I like my truck much more as a daily driver vehicle as far as how I wish to use my vehicle anyways. I believe ideally for a customer like me a supercharged truck would still better suit 90% of my driving / towing. I am a former diesel guy had many Dmax trucks and one well over 550 rwhp. Nothing pulls like a diesel nothing BUT as a DD for someone who has to commute to the city at times etc they are a PITA to park, get into parking garages (Toronto) ride rougher and handle like a truck (which they should) the 1500 series is better suited for me. I just wish it had the diesel like TQ which is what the SC adds.

They're all stuck with complying with the EPA, that's one of the big reasons. But it doesn't make any sense, they fight a horsepower game but at the same time a fuel economy game. Why not have both?? GM provides how many different configurations?!?!? Why not just make 2, one for the guy that wants awesome economy and one for the guy that wants some down low power like a truck should! Geared properly for towing. Even an economy based model would still blow the doors off of pretty much anything made even 15 years ago so what the hell??

 

As for diesels don't get me started on the whole emissions thing. Let's fill an engine bay with completely useless components that cause harm to the engine and take years of life away. Only to have a fraction cleaner emissions and put you at the pump more anyways. It all started with ULSD, the engine components don't last as long and very complicated compared to the old diesels. I don't get why you would put a DPF/egr on a truck to that robs over 5 mpg or even more. The EPA is killing the affordable diesel.

Well I agree with you regarding robbing fuel economy but as for longevity, I'm seeing DPF equipped diesels last just as long as the non DPF equipped.

When's the last time you seen a million mile 6.4 ford or LMM Duramax??

 

I'm willing to bet never. When's the last time you seen a million mile 5.9 cummins??? Or LLY/lbz? Quite a few of em. Especially cummins.

I've seen the intakes of egr equipped trucks after only 150k and it's COATED with thick black. That and the rear pistons/injectors/turbo take a beating during regen from the heat.

 

The cold side of the turbo is not supposed to be clogged with crap. In older diesels that would be a sign of problems. Nowadays they consider it "normal" lol

Oh gee.. lets see.. LMMs came out in 2007.5.. so that means... what.. 7 years since they were first released? Give it some time, son. Not everyone puts 200,000 miles a year on their trucks, ya know. You'll see em out there. The technology has been out just as long if not longer on the big rigs and they are doing juuuuuuuust fine with it. Longevity isnt a problem. :cheers:

So 07 5.9's don't count? Or 06-07 LBZ?? We've had multiple DPF equipped work trucks at work shit the bed, good ole trusty 5.9's still goin strong. Ever see a super high mile 6.7?

 

I'm not in it for a debate, IJS it ain't no secret bud. The DPF laws came I to effect the same time as light duty vehicles. In Canada, guess what vehicles are except from DPF's???? Emergency vehicles, because they have broke down on route...

And if you search DPF delete for big rigs it's not hard to find lol.

 

Useless technology

Now that's a tough call right there. DPF's came in as part of EPA '07 emission standards. There are thousands of pre-emission class 8 engines that have gone over a million without a major repair. I have yet to see ANY EPA'07 or EPA'10 engine go over 500,000 without losing either an EGR, and EGR cooler, a VG turbo actuator, DPF filter, or a cam. And when you add SCR with EPA'10, a lot have already had to replace dosing injectors or sensors. A truck owner that pulls the same customers as I do, just dropped $14,000 in repairs on his Detroit DD15 engine and emission systems. Can anyone say, ouch?

 

Gotta be one out there that has never had any issues, but it has to be about as rare as a white buffalo. And I have not figured out how you can feed an engine it's own feces and expect that it will live as long as one that doesn't, speaking of EGR. Look at soot levels in used oil samples from pre-emission engines compared to the newer emission laden stuff. Why do you think they had to develop CJ-4 classification oil? The soot was becoming a major problem. It is one thing to feed EGR to a gas engine, it is quite another to feed it to a diesel. You need not only the EGR, but a major cooling unit to cool the EGR before heading to the intake. And when one of those coolers leak, you get coolant all in the cylinders and oil. Not terrible if you can catch it early, but you are looking at a new or rebuilt engine if you don't. Good luck with that one.

 

I can't speak to the pickup diesel game as well as I can to the commercial diesel game. But, if you want to learn all the latest swear words, just pop into a truck stop and ask the drivers how they feel about these new emission diesel engines. I see a lot of these newer trucks broke down along the highway waiting to get repaired or towed. Far more than was the case on a weekly basis before this stuff all came about.

 

And when the warranty dies off of the diesel pickups that have been bought in the last few years, just wait till sticker shock hits on how much it is to repair those emission laden engines. Those poor folks who are jumping on the 1500 diesel and mid size diesel game are in for a real shock. Especially if they are coming at this as a newbie. Even I am swearing off of emission diesels for as long as possible. I am hoping that GM finalizes testing of the 3.2L EBDI engine for the 2500HD and 3500HD pickups soon. That V6 has got the same HP and Torque as a 6.6L Duramax diesel, gets better mpg, and does it all on E85! No more emission stuff than what we have on gassers now, 400 lb lighter package in the pickup, etc. Might even get offered as a power option in a future HD version of the 1500.

      Higher oil pressure after DFM shut off

      By 81mmcat · Posted

      Can anyone explain why the oil pressure runs higher after the DFM is shut off?  just installed the Pulsar Lt.

      Thanks!  I figured as such; GM and other manufacturers have used standard parts and harnesses across trim levels and such for decades.  I pulled the blank accessory cover off of my commuter van (a 2016 or so Chevy 15-passenger) years ago and found the plug for a USB outlet.  It wasn't connected to anything, though (I tried swapping in an outlet from another van).  I was a GM Tech years ago (late-90s) and was pretty familiar with my 2006.  I might be wrong, but I view newer vehicles (pretty much anything made in the past 20 years) as being a lot more plug and play.  Meaning, more unused wires and plugs unless you have the Mack Daddy of vehicles.

      not all plugs will be used.  gm uses more generic harnesses that support most/all options, and if your truck doesn't have a specfiic option, the plug won't be used (commonly will have a dummy insert in the plug , or it'll be taped up, but some may just be left as is).  But it's sldo possible some p.o. has installed the wrong/cheaper parts that aren't correct for your vehicle...

      First off, I'm not trying to just get easy advice/fixes for the issues I've noticed so far.  I'll be combing through the site via searches and such, and if past experiences are any indication, should find what I need.  For the sake of conversation, though, I figured I'd post the handful of things I've noticed in the 12 hours since buying my 2010 SLE CCSB.     Indicator lights: Airbag and TPMS.  The tire pressures aren't reading for any of the wheels, so I'm pretty certain the sensors were either removed, are damaged, or are otherwise inoperable.  I used to mount and balance tires 25 years ago but am pretty much ignorant when it comes to TPMS.  My 2006 didn't have the sensors and this might be the fourth vehicle I've owned that does.     Radio: Rear speakers aren't working.  I removed the driver's side rear door panel and checked the speaker and wiring.  I also removed the sill and b-pillar covers to check the wiring.  A few minutes of Google Fu showed that this is potentially a head unit issue.    Switches: Power mirrors don't turn left/right.  I ordered replacement driver's door switches that should arrive tomorrow.  The windows and locks work but it was only about $20 for all of them.  The driver's side rear window switch lets the window down but won't put it back up.  I think the passenger rear doesn't work at all.  In the coming days/weeks, I'll break out my multimeter to check all of that.   Unknown wiring harness: There's a box attached to the front driver's side of the engine compartment, right where the second battery shelf is located.  There are three plugs, one of which looks like it fits a standard headlight-style bulb (9007 or similar).  It doesn't look like it's plugged into anything.  I'll do some digging and if I don't see anything elsewhere on the site, post some pictures here.   Unknown plugs on brake booster: There are at least two female plugs on the brake booster that aren't being used.  I think it might be a replacement/aftermarket, so maybe those are used for a different application, as there don't seem to be any unplugged harnesses and no indicator lights are on.   Little squeaks when turning: Sounds almost like a bushing around the bed of the truck.  I'll have to pay close attention as I get more familiar with the truck.   Clunk on acceleration: possibly the infamous drivetrain clunk.  My 2006 had it and I'm just not familiar enough with this truck yet to fully grasp what it is.   Anyway, my apologies for the vague and all over the place post.  This truck is new to me, and it's been four years since I drove my 2006.  With 200k miles, I know I'll need to learn this truck quickly to avoid having any major issues, despite being confident it's got much more life to it.  My 2006 had nearly 320k on it when I parked it (nearly 300k of which I put on the truck), and it was still drivable then, though I suspected the head gasket might have blown.  I'd hoped to have that truck back by now, but it's gone forever, as I detailed in my reintroduction thread.
