Is there different 'stage 2' injectors, or is that number a common reference to them, wherever they're from?

Dang, same codes and same 'no-go' situation this morning. 95 model ol faithful's not going anywhere.  

Gday mate, welcome aboard. If the speedo sensor fails or gets dirty the the truck will derate. Should see 32ish psi. With engine idling, cruise off, hold speed set button down until light starts flashing and count how many times the yellow light flashes. Should give you 2 groups of flashes/numbers. Let us know. 

I get the same issue with my CCRS when the waste gate actuator fails. 

Maybe turntable bushes or jaw issues. 

Did the 'downgrade' hurt or improve performance?

How about has anyone detuned a 460 (software change only) back to 380 or 427?

Welcome aboard mate. 

Could well be your fuel pump, R/H front of eng. Maybe check fuel pressure or pull the pump and make sure gear is tight on the shaft. 

Thanks KS, I was looking for the current thread from Mack Technician, seems he had some 'technical issues'. Thanks again. 

Anyone know what happened to the thread with regards to the EGR-deleted 12-litre?

Ahh bugger!!

Just noticed that it's an old topic. What was the issue?

Any blink codes?

Thanks Mpro, this dog has had it's fair share of jump starting. 

Hello, does anyone know if there's a common reason for the copilot to go blank?

G'day Rowdy, was looking through this older thread and was wondering if you did fit the aftermarket parts and if so what was the results?

Hope it's not the same as my 350 which developed a bad knock and miss. 2 piece crankshaft was the problem. Good luck. 

That engine in Oz will make 1660 ft pounds, dunno what the XT gives you. 

Thanks mate, I'm gonna do something just dunno what yet. There's a mob in Melb who will send the ecu to Perth for a tweak, I'll probably start there.....I think. 

Does anyone have any thoughts (preferably based on experience) on what sort of safe & reliable HP/Torque we can get from upgrading a 470CCRS eng? It's a money earning work truck, doesn't do high annual k's, but works pulling a low loader and I can't help but to wonder if an extra 20% would make it much nicer to use. 

Which engine do you have, what are the results, did you only get the 'delete' or more than that?

Does this 'upgrade' apply to etech and CCRS engines?

G'day everyone, the speedo in my '95CHR more often than not only reads 40-50 kph, even though I'm moving at 80-100kph. Speed limiter & speed control work. New speed sensor & new speedo head/gauge fitted. Help pls....

I had an etech that did the same sorta thing. When it got lazy I'd stab the loud pedal a couple of times and off we'd go. I thought it was a computer setting type thing. 

I've had a similar type problem with my '95 vmac, runs good all day, shut down for the night and then just winds over the next morn. Turned out to be an under dash electrical issue. Big solenoid was a bit lazy, give it a bit of a 'tap' and she'd fire right up. Good luck mate.

I'd also like to know.
