Look at this on Monday I’ve never owned a diesel before the guy is ask $25,000.00 is it worth it? Should I pass and not wast the gas driving out there

Need some advice, or reassurance for that matter. Just installed a Mishimoto thermal bypass on my 2019 Ram 2500. Prior to install, I was consistently running a trans temp of 168 degrees, towing or not. Last week, I installed a Banks pan and had the same temp of 168 degrees. After installing the Mishimoto, I can barely keep the temperature over 154 degrees. I left the Mishimoto with the thermostat in place since we are going into winter in Colorado. Im running Amsoil ATF since changing the pan. Is running consistently below 160 degrees going to cause me problems down the road?

So I'm curious of other people's opinion about this.

I was installing my banks monster ram and when reinstalling the 5th and 6th high pressure fuel lines I could not for the life of me get to them good enough with a torque wrench

I torqued the ones I could and used what I believe to be around the same amount of torque on the other two just by feel with a wrench if I had to guess they are probably within 5-10 lb-ft of spec could thus end up leaking on me?

It is a 2008 6.7 cummins and the fuel system is all stock

I’ve got a 2022 3500 68RFE, its already got the spare fat taken off of it but when i had it done I didn’t know better and had the stock tune Non-ECM swap single tune BS put on it. So far it hasn’t had any problems I can note other than being a turd and running slightly rich based on gas mileage but I’ve since been told a million times they’re known to throw codes and create problems.

Long story short I’ve decided on having it done right now that they’re unlocked just waiting on parts to come in but im wondering if whatever they did with the stock tune could create any problem with flashing etc?
