435hp 5Ek help

Having the same trim numbers across the board isn't a great idea. It may live forever that way but may not.

 

You've already asked this before .
Some one told you to put a 600 file in it.
That will wake it right up.
You should also consider what turbo is on that engine. If it's still the 435hp turbo,your just asking for trouble.

 

If you had 58's, with a 550 brake saver 1LW series would of woke it right up. Like swaan says, with 57's, you need the 5DS series 601hp file. And a bigger TURBO, times 2 on asking for trouble with the small 435.

 

BTW, my 435 5EK (born)came with 58's. Maybe the other truck that out runs you has those injectors.

 

Or different gear ratio8

 

i have same problems dude.. idk wtf i keep using it and pulling 80,000-90,000 up 6% grade. it gets worse n worse then misses cold start clears up then dead misses i change #4 injector and start over till its dead miss again. 3 times now. #### a 3406E and shove them steel pistons up them cat mechanics ###. aluminum pistons are just fine till 1100°F they crack but doesnt effect it.

 

im used lil baby turbos b4 on B model engine. and used the low hp nozzles and still outrun everything. oil got hot from turbo. it worked tho. i got a big B model turbo on this E model. its just a p.o.s. Engine
