My Opinion..... DONT DO IT!

They add a LOT more fuel and egts sky rocket...


Just my opinion... The choice is yours. :c:

I agree on not doing laser cuts unless you plan on going to some sled pulls. Fill out your signature so we know what you've done to your truck, that'll help alot. I would look into doing 191s which is a big difference than the stock DVS

X3 laser cuts are great if you're running a huge set of twins have a block girdle 14 mm main studs and head studs billet rods pistons pushrods. A huge cam big ass injectors injector lines and have a pump built to use them. So yea 191s or even 181s do the job just fine

I would think about going to a different shop for the pump work. Delivery valves are just about the last thing to do....and lazer cuts are out of the question for you at this stage of the game.

I asked him in an email what the lazer valves do and here is what he said..


"Delivery valves are the 6 little 'outlets' from the injection pump...and they can be a restriction between the pump and the injectors. Basically, by swapping out the DV's, you are ensuring that your stock injectors are the restriction (as they should be) and not something between them and the pump. governor springs, advancing the pump timing, a ground fuel plate, should be "first"...but the delivery valves do wake them up a good bit more, and they are pretty "cheap".

you have a long way to go before your 181 dv's become a restriction many have made over 500 rwhp with 181 dv's

You will just gain heat and smoke.

OK so the lazer dv's are out. Now i need to find another diesel shop that knows whats goin on with these trucks. The shop i got this from deals mostly with the 7.3, and thats how i knew about them, they did awsome on my 2001 ford 7.3. but he did say hes only messed with a couple 12v's..

All DV's are going to do is add lots of heat
