Yeah I am definitely going to make I breathe better don’t now much about the ASET delete but I am going to put a fleet air filter on it and upgrade the exhaust Mack technicians way with a older exhaust manifold. I just don’t now if spending $2000 on a polished one would be worth it

Isn’t that truth

No sir. you are not being mean at all. this is why ask questions because I am not a now it all. With out people giving responses like you have nobody learns anything even just telling somebody to use graphs and what things to account for helps. I understand there is no magic combination. That is why I ask questions and do my homework before I spend money. If I just spent money when ever an idea popped in my head with out doing this I would make a lot of stupid decisions.

Awnsers like this is what I am looking for. This truck was specked for the hills of PA and I live on the coast of NC. So everything is fairly flat and I mostly haul asphalt and rock 98% of the time. I am very rarely in a sand mine. But if my conclusion is I need to leave it alone I am fine with that. But if there is improvements I can make I would like to you know what I mean

I have been doing my homework “hence asking questions on here” and I have some ideas. But I I am a big advocate of asking other people as well to see what their experiences have been like. To further my knowledge and try to make the best informed decisions I can make. So I just don’t throw money at it hoping it works.

Yeah my question is how high of gear do I need to go to and hopefully an estimate on the improvements in the MPG.

Yeah it’s a stock Mack with mack rears. I have read through that and that project is in the works maybe not the injectors right now. but definitely helping my dog breathe better. But only having that 10 speed keeps my rpms so high with those 4.64 gears. Wasn’t sure how much of an improvement I will get just by fixinig the exhaust side.

I Currently have a 2004 cv713 quad dump truck the truck never totes over 70000 pounds. The motor is a Ami. 370 a t310MLR trans, 4.64 gears and 24.5 tires. Truck currently runs at 1475-1500 rpms at 55 mph averaging 6 mpg. Considering gearing higher to bring my rpms down to somewhere around 1275-1300 at 55mph. Not to concerned about power but just wanting better fuel efficiency. But not sure if the motors power curve can handle that.

Can anybody give me that part number for the steering gear box? last 6 of my vin is 009095. I would greatly appreciate it.

Joey I haven’t had the cal code entered yet but after about a hour of running with the new eup the random miss has gone away and my turbo is now working like it is supposed to. Thanks and also that bolt length was 40MM I appreciate all your help on this situation. I am sure I will be asking more questions soon.

Yeah #6 wasn’t too bad changed it out this morning. The motor sure is running better the miss seems to be gone. how important is it to get to a dealer to have it programmed?

I have a 2004 ami370 was hoping he found a solution

Myne does something similar as well it will be pulling making 30 pounds of boost and then all the sudden it’s like you take your foot half way off the throttle. The truck will stop pulling and the boost gauge will fall back to 18-20 pounds sit there for about 5 seconds then jump right back to 30 pounds and go back to pulling. I have been trying to figure it out and it is aggravating as hell.

Did you ever figure out how to fix this problem

Thanks again JOJO.
