    Mark is tuning though so I would think with absolute certainty that isn't the issue.

    Fuel pressure regulator

    I dont think the engine needs the fpr to run, it'll make max rail without it is what 2004LB7 is saying. Hook efi up and log FRP and DFRP see what it says while cranking.

    What kind of lift pump is on the truck? Maybe it isn't keeping up to duals and big sticks.

    Get a P.O. Box in Manitoba then register your vehicle for that province then just pay the bit extra insurance to work 'out of province' lol

    Duck the MANN or throw in the towel?

    Where in Canada emission tests? I've read Ontario does for it but that is one garbage province, I'd rather drink gasoline than live there. I've never heard of any other province or territory doing it.

    I guess if they did that I'd pull the motor and trans and part it out give them the shell to crush. What a throw away society we live in. Don't want to/can't afford to put a dpf back on? No worries we'll crush your truck so you can buy a new one because that's better for the environment.

    If it were me I'd get some DDP, exergy or S&S injectors like Brad mentioned. Injectors that aren't good will make these trucks run like shit. I'm curious , what's the calculated fuel rate mm3 at idle and warmed up to temp? My new ones are 12-13mm3 and my worn out ones were down to 6-7mm3 and...

    I've read the T5 15-40 conventionalcan give injector issues with some not sure about the truth with that. I know I've always been concerned about cracked piston broken crank problems and so far the T6 has proven to work for me, even my oil pressure when hot is just as good as when I bought the...

    Well 37s are big tires, alot of weight there. I have 35s on 22s and my truck on tune 4 will barely squeak then unless it's cold or wet out. I'm thinking those nozzles could be some your issue. You need some actual 100s on there or bigger even 150s with your setup to drive those. I'd send them...

    Gut a stock dpf and put it back in if it's just a visual and use one of your dsp tune spots for a clean snap test tune. That or move to Canada we don't know what smog is yet haha.

    That would definitely be why there is light black smoke lugging through town.

    What rpm are you lugging at when it smokes black and what rpm is it when it's cleared up? What size tires are you running? Whose injector is it? I've never heard of a 67% over. What torque converter do you have in it?

    Next Mod Help

    I meant the oem piping. The lift pump is a good mod for these trucks regardless if your truck is having fueling issues or not.
