Chris, SOTP feeling with Bill"s tunes is awsome. the truck is very smooth and just pulls and pulls. with Jody's tunes it always felt kinda like a 2 stroke bike. By that I mean pipey, you had to hit the power band and then it pulled. that feeling is all gone. now it just goes.

More info in my truck clean fuel filter, 60-65 psi at WOT, Tymar filter with Big Boost AFE, 5 in exhaust DFA CCK fuel mods

 

Hey Barney,

That sounds awesome! Glad we could make you smile. Bill definitely wants to get a second look at the high hp program. The biggest reason the pressure is dropping is because of the pulse width; he definitely needs to readdress that (that came directly from Bill -- I don't pretend to know what I'm talking about -- now, you wanna talk F-150s? I am SO there. )

Bob mentioned you'd be swinging down this direction in a few weeks. If for some reason your plans change, no worries! Bill (and maybe the boys and I!) will be going out to Washington in July for Dynomite's Grand Opening of their new shop and Dyno Day. He will be arriving a few days early so that he can live tune some customers' trucks (this ISN'T part of Dynomite's weekend -- it's a PHP thing).

 

This is the first time I have ever heard that somebody elses chip works better that a DP.

 

Even still, with the Adrenaline you are dropping more pressure than you should. Back when I had my bone stock HPOP I was maintaining 2100-2200 psi of ICP in the 120 hp race tune, which had more pulsewidth than Jody's 80E tune.

That's why I figured something was wrong. Bob has been doing a lot of testing with the Adrenaline and AFAIK yours is the first pump to be losing pressure like this. Your numbers at idle may be fine, but I'm just curious if there is something else happening that's causing this issue like a bad injector o-ring or an injector pissing oil out.

As for custom tuning, yes Bill can make adjustments to try and keep ICP higher. Still it doesn't address what's really happening, and is potentially only a bandaid fix if there is in fact something else wrong.

It happens Dan. Bill, Tony, Jody, David, and others have done quite a bit with their tuning. Every customer has their own preferences, and sometimes they like the tuning styles that a different person puts into the programs. That's why I did live tuning on my truck. I liked Jody's standard tunes, but they didn't quite match up to the way I really wanted my truck to drive. He made a lot of changes to my programs and they vary quite a bit from the original tunes. I think being a tuner is one of the hardest jobs to have in the PSD world, because so many customers have such different trucks and different driving styles. It's impossible to find a "one shoe fits all" tune.

 

Well-stated, Curtis. Takes nothing away from any, gives credit to all, and I have personally reached that same conclusion just from watching on the sidelines for the past couple of years.

 

Shot through the heart, it does'nt sound like it is up to par, you should not have to do this, do that to make it work. NA!

 

What a bummer............Was saving for one.

 

This is the question that has been in my head since first hearing about the adrenaline.

 

With no chip and stock injectors 2750 seems iffy to me.

I know, I know. As long as I don't get laid of on Friday I'll definitely have it done Saturday. Actually, I'll do it Saturday even if I do get laid off. It's paid for.

I do have a question.....Where in the system is the pop off valve? The IPR regulates the pressure, up to 4000 psi where the book says there is a mechanical pop off valve there to protect the injectors. Is the pop off valve part of the pump, or is it built into the front cover, or the engine, or what? I keep re-reading Barney's post and I just keep thinking something is bleeding off way too much pressure.

What if a poppet in an injector was stuck open and the HPO was pumping straight through? Could that do it? A buzz test would find that right?

Another one

A pretty cool thread with dyno results, too!

 

Not to take anything from anyone here but how old were your tunes Barney? I'm glad that your happy with the PHP but if the tunes on that were "newer" and the DP had an "older" set of tunes would that make a difference?

 

okay okay, I' ve been busy beating my head against a 6.0. so i missed all this. I agree with Pete and Curtis, tuners all have their styles. And I'm Not Throwing Rocks at Anybody! I believe the pump will put out 4000 PSI and i think if you've got jody's tunes and like them, thats great. What I believe I'm fighting is the fact that my truck is an F550 and nobody and I mean nobody has my computer code in their data base. I've fought this battle before. Ford factory settings limit my HPOP to 2750 period. F250 or 350 are different. If you drive a "little" truck you should have no issues at all. The Adrenaline will put out what ever your demand is if your computer will let it.
Curtis the injector buzz test comes up fine and cylinder contribution comes up very good.
Corey, thanks for the offer. but I'm pretty sure I'll be in the Atlanta area so we should be able to touch base there. Tell Bill THANK YOU for the prompt service.

Barney

 

Sorry if that sounded off Barney. I was just asking out of my curiosity, wondering if there was a difference from some years on the tunes.
Thanks for posting all of this info for us.

 

F550 is a VXY2 tune. F550 specific.

 

Sometimes being unique isn't so great.... mine will hopefully be in this weekend. I may be running up to South Dakota too, a nice little break-in run! LOL
