Start with getting an air filter and a filter kit (should be done anyway) and then put a load on it and see what happens. If you still have the same results pressure test the charge air system and check for exhaust leaks. Quote Link to comment Share on other sites More sharing options...
Bliue dm Posted March 12, 2022 Author Share Posted March 12, 2022 Well it's a 2000. I haven't ran it loaded. I guess my confusion comes in is this. I've driven quiet a few e7400 with s400 on them. On a cold night loaded I've seen 32ilbs of boost. It's only suppose to be a 400 tho. 95 percent of the time 28 -30lbs of boost. If 30 to 32 is it for a 460; how is mack making the extra 60hp?

Changed hot side boot from turbo to intercooler. Definitely filters tomorrow. Quote Link to comment Share on other sites More sharing options...

Onyx610 Posted March 12, 2022 Share Posted March 12, 2022 No boost leaks/exhaust leaks it could be a shit turbo or a worn out engine too. But I wouldn’t worry about a few psi. Every engine has different ranges even when they are new. Quote Link to comment Share on other sites More sharing options...

Bliue dm Posted March 12, 2022 Author Share Posted March 12, 2022 It donest have any blow by. It has a new cam and few other things in that area. Does anybody know what turbos they replace them with. It's already a borgwarner so I'm assuming the same one if it was weak? Quote Link to comment Share on other sites More sharing options...

Correct, I think it was white/red key color and I think it was just turned around for less or more. But yes programming, if your familiar with diesel pickups and tuners you know that well over 60hp can be achieved with the tunes and all stock injectors and turbo. It’s just all through timing and duration Edited March 12, 2022 by Onyx610 Quote Link to comment Share on other sites More sharing options...

Every engine has different ranges even when they are new. WHAT ony is talking there is where you need to be looking at! FIRST! Eliminate what you can before throwing parts Waste of money otherwise! and yup it could be a bad turbo However! Things to look for are Black smoke under load High pyrometer readings! check for boost leaks check the compressor inlet tube hose real common leak there! just sayin don't jump to conclusion on a turbo!

Onyx610 Posted March 12, 2022 Share Posted March 12, 2022 Fjh is one to really pay attention to like Joey Mack vmac3 and MackPro. There’s alot more but they are on here the most. Change your filters and make sure that notorious exhaust manifold isn’t leaking. Then let us know what happens. Quote Link to comment Share on other sites More sharing options...

Onyx610 Posted March 12, 2022 Share Posted March 12, 2022 Looks like your in New England area with those patriots stickers 👎🏻 Make sure that road salt isn’t beating the hell out of your radiator/intercooler. We see a lot of that down here in PA. A lot of radiators get replaced…. Quote Link to comment Share on other sites More sharing options...
