Has anybody heard or performed a "90deg" injector bump on a 3406E Cat before? I heard it is suppose to be a good power increase but can't find any info on performing it.

I ve heard of it being done and the power gain is good. my brother did this to his 02 C-15 accert worked perdy **** slick.

There used to be a link to 3406B hot rod tips. Don't know the difference between the E & B. Might try a search for 3406B.

The 3406E is more of electronic engine since 1996 to 1999 and the 3406B is older like late 80's and early 90's series engine mechanical.

Ya Im looking for info on the electronics 3406E's specifically a 550 but a 475 is also setup the same

Sounds like its a fuel timing change... never heard of it, but if you get info on exactly whats being changed, post it. Why not just go with a re-rate?

Underpsi

Whats re-rate?

Diesel Doc

send the computer to cat and have them change it for you. If you have a 550 e already they wont go any farther but their are companies out their that make black boxes for them to add like 200hp or more

There's the pittsburg power but no way im paying over $2000 when I know there is power to be had for free. Plus I can pay Cat $700 to dyno it and set everything up

I stay up-to-date on any and all performance upgrades--or atleast try to--and I have NEVER heard of what you guys are trying to do here with a 3406E. Nor do I think that its possible for the average guys to come up with a feature such as this to manipulate ECM timimg and injection duration changes without some form of a "box"

Underpsi

Somebody at a dealership told me about the injector bump. He said its a common thing for a good power boost and the 3406Es

catdiesel

that guy must be "special" REALLY "special"

Underpsi

He actually seems like he knows what hes talking about

catdiesel

youve got 2 CAT engine field specialists on here telling you they've never heard of it......... But your entitled your own thoughts and opinions.

PoorMansCat

Hey Catdiesel, sounds like somebody has decided that cranking on the injector adjuster screws (whether advancing or retarding the injector timing) is making more power. hhmmm.. surely not.....
