i ave heard that they are the best pressure box out there. I was wondering what kind of performance gains i could expect on my 05 compared to the ez? i am looking for the module that does pressure only. One more question, where could i get one and what do they cost, thanks.

 

They have a few options in your case one being the 2017 and the 2021 ones a 85hp and the other is 110. They retail for over 500. They are a progressive pressure box, I have owned one and liked it.

 

thanks CReed what do you mean by a progressive pressure box

 

They also have a 140hp box which is pretty extreme. I had the 110hp and then sent it back to get the 140hp flash and there is a noticable difference.

 

a guy just pm'ed me he has a 140hp box for sale will it work on an 05 or are they year specific? if it is 140 then it should be a noticable difference over the ez?

 

Do you have aftermarket injectors or cp3 work done? You may throw a high rail pressure code with the big stage IV module on a near stock truck but if injector mods have been made then you should be okay. Progressive means it doesnt just spike the pressure up it brings it in on a new fueling curve bit by bit, not all at once like some others that are hard on injectors.

 

what are stock pressures in the rail, and then what does the ez raise these numbers to on say settings 1,2 and 3 , for people who have a rail pressure guage any way it will ever get to 30,000 psi?

 

Stock relief valve will blow at 27500 you should see 30k ever.
