I got my through applied.com distributor for $42.

Thanks, That’s a rubber reducer. I tried looking on there site and couldn’t find it.

How's that 370 map? What do you think?

Thanks! I ordered one. The bottom of mine had some cracks and might be letting unfiltered air in.

I just took it for a spin around the neighborhood last night to make sure everything was hooked up right, some time this week I'll take it on the highway to check it out for real. Runs smooth and actually seems to idle a bit quieter according to my phone's dB meter. Not sure why that is, the turbo blanket shouldn't make much difference at idle but I'm happy with any reduction.

Probably the newer map has more refined injection timing. Injection timing and number of injection events per combustion stroke (yes there can be more than one) all plays a HUGE part in the noise of the engine at idle. Had a rep from Isuzu that showed us how he could dramatically change the engine sound and make it significantly quieter with their stratified injection that used multiple injection events at idle to reduce engine noise significantly. So much so that with it on vs. off made the difference of being able to talk to someone near the machine or requiring ear-pro.

All of the many changes I've made to my truck - ECO hubs, engine mounts, 370 HP map, etc - in conjunction with the A1R insulation already present - it is astonishing to get back into an unmodified truck and realize just how much improvement I have made. It's a totally different truck really,

Just had a new fuel line made and I didn’t notice until I got home that the hose shop used 5/16” ID nylon hose instead of 3/8”. Should I have them remake me a 3/8” hose, or will 5/16” suffice? With the 370 hp tune I don’t want to run into fuel starvation issues due to fuel line restrictions.

If error was shops, definitely have remade. Your error? What is max fluid flow from 5/16 @ prescribed pressure? What is max fluid flow for 3/8" @ prescribed pressure? If amount is negligible, and I do mean small, then you could try it. I would simply have hose remade, done and over with.....KISS (Keep It Simple S$#pid)

Shop's error, I handed them the original hose and asked for an identical one. Original is 3/8" hose with 3/8" JIC 6 fittings, so I'm not sure why they made me one with 5/16" hose with the 3/8" fittings. I'll take it back tomorrow and ask for one with the correct 3/8" hose.

Flow rate is hard to estimate as it gets into length of the hose, number and degree of bends in the hose, etc. Easier to just replace like for like and not have unintended consequences.

Finally got the correct fuel hose installed. The hose shop tried to tell me that 5/16" ID hose is the same as 3/8" ID hose because they both use a JIC 6 fitting, so I had to educate them a bit before they would make me a new one.





While I had the cab up I also replaced the passenger side lower cab bushing, ran out of daylight before I got to the driver's side.



And yet again I found another item to add the to-do list, the drag link boots have disintegrated so I ordered some Energy Suspension 9.13126G boots to replace them.

Yeah. Congratulations on fixing the bushing!
You will feel a difference in the "ride quality" immediately.

Sad to say, the other side is a bit more of a PITA to get at...
