You have it stacked for adjustability and that only. Your not gonna get maximum horspower say if you have and edge juice with smarty turned all the way up as if you had the edge juice and got an ez. Smarty or BDDL and a pressure stack would work the best for maximum hp. You turn that Smarty all the way up and start bumping the juice and see what hp you get. Have you dynoed the stack. I dynoed the bully dog on extreme setting and got 355hp and bumped the juice up to level 5 and got 366hp and alot of timing rattle. That was before my current mods and everything was stock. I think you would be best of with a pressure stack or get a downloader and keep it turned down like omahram. The Edge Juice is just for the average guy wanting average hp. If you want big hp you need to run a downloader or TST or something. For an 03 I would look at a Smarty they do wonders on them trucks. I agree though at the point were you have to be satisfied or look at dumping a good 2500 or so into it probably more.

 

I am running the J/A hot flashed with glacier pump and just got an ez to stack with it. I have read that with the mp-8 you don't want to go over about 40% with it stacked to keep from cracking injectors, what about my set up with the ez? Which level is safe to run? I do have a r/p and fuel pressure gauge. Also, which is the best way to stack the ez and the r/p gauge. Does the gauge plug into the sensor first, or the ez?

 

Sorry, didn't mean to seem like I am hyjacking thread, just basically on the same track as you.

 

hey sqrl$$ I have the juice and ez, I cracked an injector within a week of puttin the ez on. I unhooked it and pulled my injectors last night. I was runnning it on #3 and juice on 6, it might be alright if you didn't max it out but I won't take the chance again.

 

any idea of what rail pressures you were running?
