Fumble with the 1939 J our 93 was doing the exact same thing. Would randomly shut down but flip the key and it would start right back up

Throw a s475 on and hang the F on. You got enough fuel to spool it

Post turbo probe? I would keep try to keep it under 1050. Our says 1025 max and 99 says 1100 max. 1200 won't hurt it for short bursts but deff don't pull a couple mile grade like that

Your boost sounds a bit low. Think it should be 28 at the min to 32. Don't have the book in front of me now. They have 2 piece piston. Steel top/alum skirt. Give mack the ser# to find out what comp pistons it has. They were all over the place in diff years. For example the 93's 250-400 all had 16.9:1 (conflicting info around) some literature says 375 and up 15.3 and below that 16.5 but mack had changes over the yrs. One book said our 93 was 16 5 and another 16.9. It ended up being 16.9:1 (591 tops) I doubt it's 16.9 could be 16.5 15.7 or 15.3

Throwing any codes? The boost i feel should be higher. Someone familiar with 427 should chime in and say for sure what boost you should be seeing but IMO it seems off. If you don't have access to code reader w/Vmac3 card send me a pm. I have pro-link 9000 with Vmac3 card

28 psi seems a bit low. I thought 427 file was somewhere around 34-36psi. We're 10 min south of Binghamton Don't listen to those guys. We've dealt with d&w before. By law they can't do any hp increase due to emission regs. I haven't heard of injectors cracking and there is a lot of guys running stage 2 & 3 on here. Antrim has dyno'd a few E-7s putting 700+ to the ground. Since you just put new injectors in I'd go with the Blixxton. It made the 460 a completely diff animal. I think you'll be happy with just that. Seat of the pants dyno felt like 100+ hp easily.

EGR thanks to the EPA. A little bit of $$ will fix that permanently

You can pick up those 475's for 600 new. In order to gain anything though you have to do injectors at the same time otherwise that'll be too much turbo. The last few days up here in the 90s we haven't had any heat issues either. Turn the fan on bottom of a hill and water temp maybe hits 215-220 on a hard pull running close to 80k

Leave the 427 file in it. Has a better torque curve than the 460. Antrim in Greencastle pa is really good performance shop that does a lot of E-7s. Blixxton has a plug and play tuner but im not sure if it works on CCRS E-7? We put one on a 99 460 and it was night and day difference in power and gained .75mpg. Huge puff of smoke between shifts but clears up real quick and 850-875 is hot as pyro gets and 38 psi on a cold morning. Some guys here with bigger injectors are pushing 45+ psi. If you do a lot of stop and go city driving the BW S467 (1.15 A/R i believe) has good throttle re

Every now and then going from High to low range in t2180 will go BANG. Not every time tho. Someone's been in the back box before. Still holding together but she's LOUD. The old school double over in the 93 is quieter LOL

Should be ht550? Not a fan of them, previous owner might of done the viscous. Shit design, the little bit grease it has gets blown out after a while and seizes up.

On the 93 350 after doing an inframe, blixxton, turbo & injectors we saw roughly 1-1.5 mpg gain

Keep that 95 you'll be glad you did. If any mpg gain at all, the added maintenance cost will offset the difference. On a 99 etech 460 with 4.42 were seeing 6.1-6.3 avg running PA/NJ doing the speed limit. Around 7.3 with the 93 avg 60k loads

Just figured I'd relay what they told the old man the other day at Cook Brothers in Binghamton. Said they are having trouble getting them. Mother Volvo is phasing them out i bet. If ya got em hang on to em. We have 2 and 2 vmac1 pumps. Guy on another forum has no issues getting a head for his A model cat directly from cat. Say it ain't so

If that doesn't work It's probably one of the wires on the deutsch plug (9 pin connector going into the gov housing) J1939, possibly timing event marker. Check for continuity in all the wires. I know it's tedious but that will give you piece of mind it's not that. That's another issue. How does it start? If it's starting like normal, evens out after the oil psi picks up you can probably rule out the econovance going bad. When it stumbles/studders does it throw out white smoke or smell raw unburnt fuel? I'm betting its deutsch plug we had same issue before. I could very
