Gm screwed up there and has only in recent times improved. For all intents their "offroad" packages are simply appearance and the small suspension changes are all available with the NHT package beyond the Rancho shocks. Oh you want a particular interior package and body color bumpers and grill... well then you can't get the better trailering group.... Just dumb lol. At least now you can get these things and option trucks like the RST trim with the NHT option.
SierraHD17 replied to Snorat's topic in 6.6L Gas V8 & HD Transmission Powertrain (L8T/MYD)Its encryption and honestly let's be real here... who buys these trucks mostly? Fleets. There is no care for custom tuning with fleet operators. It's like the 6 liter with the e78 ecm since 2011. Yes you can half ass tune them but it's only half ass. Ask anyone who tries to cam one or run a supercharger etc... Guys that grab L96s for a swap like to toss the e78 in the trash and go for an e38 because it has full tuning support. I can see guys that swap this 6.6 just using the e92 that the 2014 through 2018 half tons, Camaros and Corvettes use. You will likely be waiting a very long time for any real tuning for these trucks. The Ford is not really encrypted, Ford themsleves seem to be driving customization to a degree, and honestly there is a lot more fanfare for the 7.3 anyway.. hence they have tuning. Ford pushing the 7.3 out as a crate engine with ecm and harness for swap purposes really helps here lol.
Sure. I'm good with the 63 thanks. Done with the thread.
You have the internet... do your own research just like I can. I'm the only one? From what... 4 people in this thread lol. Okay. Google is your friend. Bobistheoilgiy has lengthy discussions on this.
Pretty much.. or an EA017 Amsoil which I generally use. People get so bent out of shape over something they don't even understand lol. It's a can with media in it... GM says not to use one with a bypass spec less than oem... the 63 is not less than the 48.. voila.
Let's see here... now you have 2 conflicting opinions supposedly backed by GM documentation as the 63 is the higher bypass for the newer engines and the stubby old 48 is definitely not.. lol. This ****** is hilarious... You can use the 63 on an LS with no detrimental effect... but hey... do whatever you want lol.
05 to 07 are direct bolt in. Only pickup trucks and not any of the Avalanches or SUVs as they are coil spring. Look for GT4 on the RPO sticker and of course G80. Starting in 2005 the 1/2 tons all went to drum rear brakes so that's why I say 05 to 07. Anything 04 or older would have rear discs.
So that was taken in May of 2016. I installed that exhaust in October of 2015 lol. No my truck didn't look like the Titanic underneath and still looked great. The factory exhaust would have held up better than this did and the head pipe of course did. I sent these photos and proof of purchase to MBRP to see what their response was. MBRP said that this level of pitting and corrosion was totally normal for their T409 systems in that time frame. Funny... I have had a Magnaflow T409 stainless exhaust on my 05 1500HD for 4 or 5 years now and it still looks nicer than this MBRP did after 8 months on my truck. You can see where i scrubbed the hell out of it with metal polish and a scothbrite and all the pitting it had. No thanks. My 2017 has stock piping (it's an HD so its 3.5") and a muffler swap.. the oem exhaust still looks more or less new after 3 years now lol. Great product MBRP lol. You get what you pay for.
Yup. I took the MBRP off my last Silverado and replaced if with a Borla ATAK... what I wanted and should have bought in the first place. I might have pictures of my old MBRP to show you how terrible it was in around 9 months time.
I have had 4 different MBRP systems and after my Silverado enough was enough. It rusts bad if you drive where they salt the roads... in less than a year I had corrosion and pitting I would expect from a 5 year old exhaust system and I live where we actually don't salt all that heavily or often because it's usually too cold for it to be effective. The black powder coating also fell off almost immediately on 3 different tips I had and one full system. Hell water running down the inner panels of the box and running across the tip took off the "powdercoat". Rustoleum paint honestly held up better than their powder coating did and I could wire wheel the powdercoat off like I was cheap paint. I will never buy anything from MBRP ever again. If I want cheap junk I will buy aluminumized pipe from an exhaust shop.
No.. because it has a higher bypass differential which honestly is kind of meaningless. The 6 liters don't have any sophisticated dual stage oil pumps... it's just a gerotor pump with a relief valve in it exactly how they have been since 1997... All this means is you would need 7 psi higher differential across the filter to cause the filter to bypass oil without running it through the filter media Have you seen an oil pressure loss ever? No... and you won't. Dealers everywhere do it as the 63 is way more common than the 48. If you want to check around GM and Delco say the 63 is a replacement for the 48. Just use the pf63... That bulletin posted above just re-enforces that by stating not to use a filter with a lower PSI differential lol.
Some of you should go get your truck stuck after you have pushed until you see the squiggly and see if you can move.. you are going to have a big surprise when you walk home. This garbage is useless but necessary as people are too lazy to learn how to drive.
I wasn't saying no blackbear doesnt... didn't even address that. I'm an efilive tuner lol... yes so is Blackbear. You commented how they are slow so try someone else.
No... because you have to pay to license that file which if the autocal allows sure but I don't think it does. Search efi live tuners.... don't lol.
