2015 LML Power Steering help

Power steering help

2015 LML Duramax poor power steering assist at low RPM’s. Turns fine when you are going 15+. Cold starts, and low speeds cause worse steering assist. Replaced power steering pump with a new GM unit and it didn’t help. Thoughts?

LML fuel pressure light

Have an LML with an airdog2 in it. It’s stock but deleted. It’s only got 50k on it right now and everything has been good except from the 9th injector and back which is now taken care of. I would like to add a fuel pressure warning light or something somewhere to come on at under like 14 psi or something. All the kits I see are a few hundred dollars and you have to add this gauge pod or get a whole additional screen which idgaf about. I just want to be able address a fuel pressure issue before it takes out my cp4. Anyone got any pointers? I’m having a hard time finding some sort of sensor switch at those low numbers.

EZ Lynk tuning but not deleting

My 2018 l5p is currently about to go into limp mode because of the low def fluid warning, I have a long drive coming up soon and don’t have time to do the full delete before then. Is it okay to just tune it and drive it not deleted?

2005 Duramax 2WD & Manual Trans. Good buy or Pass?

hey y’all,

really interested in this truck. Attached a pic and the specs. Black, crew cab, manual trans, 2wd. Has to be a very rare truck I would imagine. The truck is basically mint otherwise. Inside outside underneath are beautiful. Looks like I can get it 20k out the door. Not looking for a quick flip but will this hold any value at all being 2wd? I’m in the north east so this truck seems like a unicorn. Thanks in advance.

Due to diesel trucks looks like one injector is going bad. Can I replace one injector on cylinder eight without having any issues or is this normal flow rate?

Delete tuner?

so hypothetically if a feller wanted to delete an LMM (for offroad purposes of course) which tuner would you guys recommend? been thinking about H&S mini max v1 or v2, is the v2 that much better? what other tuners do you guys recommend? looking for reliability and ease of use/setup without spending thousands of dollars

Diesel vs gas 6.6

Currently have a 2021 duramax 2500 at4. It’s paid for. Maintained well. Runs and drives great. Just over 60k miles on it. 107k kms. I drive about 5-7k miles a year. I bought it used a few years back. I love it. Only use it for camping really. But diesel is getting stupid. While way more fun to drive I find it’s getting pretty hard to justify. Prices here in Canada are 208.9/ litre. 5.70 us per gallon approximately. It may fluctuate but the trend will continue to go up over time as gas will too but diesel will always be higher and inflate more over time in my opinion. So I’ve been toying with the idea of going to a 2500 gas. I started looking and it seems the premium on diesels used to have is no longer. On average in my area diesels would always sell used for higher. Hold their value and of course still cost more new. It seems like in the used market gas and diesels are about the same. Have I missed the boat already and gas 2500s are now the same price and more in demand because of the fuel price? I thought I would get ahead of this but looks like I’ve already missed the boat. Anyone seeing HD trucks gas trucks listed within a 1-2000 difference from the equivalent diesel truck?
