That's not terrible, you considered EFI live or an exhaust?

1. EFI Live DOES NOT support the LML motor

2. the LML's have a flash memory meaning ANY time you were to hook up ANY type of programmer there will be a record that the computer was flashed thus voiding my 6 year 100,000 mile warranty, which i'm NOT willing to do. plus H&S is the only programmer that you can really mess with the motor and there a lot of issues with it.

3. ANY DPF back exhaust is a LOOKS ONLY exhaust it WILL NOT change performance or sound. The only way to gain sound or performance is to remove the DPF and DEF which will void the warranty and make the truck ILLEGAL to have on the road AND you will need H&S to turn off all the lights that will be coming on.

 

the short answer is no, i will not tune the truck and i will POSSIBLY be putting a DPF back exhaust on if i can find one cheap and that looks absolutely fantastic since it will do absolutely nothing for performance or sound

Your truck looks amazing....nice work! Quick question, are your bed rail protectors the GM ones? I like how low profile and sleek they are!!

Very nice sir. Well played. :cheers:

 

I applaud you for not trying to mess with the LML. Sure the DEF system has had a few quirps but overall the engine is an impressive piece, stock.

i REALLY hope your joking, because i don't have bed rail protectors. i do have a tonneau cover though, which i believe is what you are mistaking for bedrail covers. it doesn't look anything like bed rail protectors to me though lol, looks like a tonneau

      Some Assembly is Required

      By Grumpy Bear · Posted

      How many years have I pointed out every point in that link to the folks here and been avalanched with criticisms and outright hostilities at times? I ran counter to even the great CUSTOMBOSS and Lake Speed Jr and the half dozen experts on YouTube and in the final.....GM, Physics (Stribeck) backs that Grumpy old Bear.    Honestly, I never said a thing engineering hadn't studied silly and laid in concrete during WWII. But I'm old, the information is old and yet, the Laws of Physics are eternal.    Okay there is one exception. I vehemently disagree with their use of the word 'tolerances' when what it meant is "clearance".   The clearance is the distance between two objects. The tolerance is the degree of acceptable variation permitted in that clearance. I.E., piston to bore clearance is 0.004" with a tolerance of +/- .0002" so the clearance is in specification if it lies between 0.0038" and 0.0042". Cutting that 'tolerance in half has ZERO impact on lubrication requirements. Makes for more difficulty in manufacturing.  But a tighter clearance 'MAY'. Depends on finish. Anyway....   It's one of those statements made by people to make themselves look smarter than they are to convince people who are as un-enlighten as they seem to manipulate their behaviors. But hey, the blind leading the blind puts them both in the pit.

      Gas Prices

      By Grumpy Bear · Posted

      Out and about yesterday on a long Saturday drive I passed a lot of Shell stations. My preferred, so I pay attention. Lot's of small town Illinois so not six stations in three blocks like the city.    Everyone of them over a radius of say 100 miles had regular at $4.19 but one which was the one closest to home at $4.15. However Premium pricing varied greatly between 85 cents over regular to $1.50 over. I'm not counting the price of the station with the lowest regular so the reference is the same for the remainder and all within the same brand. However the spread discrepancy holds across all brands.     @txab, any thoughts on that?

      Future GMC Jimmy

      By revrnd · Posted

      What are your thoughts? The Chevy Blazer relaunch was an epic case of 'lunchbag letdown'. Jeep Wranglers and Ford Broncos stick out like a sore thumb.    The AI photos do not look like a 'retro version', but shrunken Tahoes. Get away from the 'futuristic look'. I've seen two concepts. One had rectangular headlight like a Rivian and the other way to big should include dual round headlights like the early version.   If not this would look OK   At least it has GM styling (albeit the K2XX) A lot of the images floating around look like Bronco IIs or the current Bronco. Looking at the Broncos in my area (central Ontario, it seems to be a mix of 2 doors and 4 doors, 'mall rated' to ones that could go offroad.    I'm sure a AT4 and AT4X RPOs could be outfitted similar to a Rubicon if the braintrust understood the whole offroad scene. Crosing my fingers that if it does see the light that the front air dam/bumper doesn't extend below the center line of the tire...

      And overpriced. I was in the Oshawa Truck Plant when they were being built. Very few. I could count on one hand how many I've seen since
