Besides if it was open all the way up the compression stroke it would make no power at all. Sal posted earlier he had the same lack of tuning capability when running a KB at 20 psi boost pressure on another L that had stock heads.

So that leads us to believe that it's got to be something independant to each cylinder. So either the Plasma Booster, or the piece of crap 50lb injectors I told Rob not to buy. The 50s have horrible issues of inconsistant flow rates.

i guess ill just go for the 60's too
but why are the 50's not working well? alot of guys have them and i have not seen this problem so prominate. but it does make sense that that could be the issue with the plugs along with the funked up PB
maybe also with the boost being so high may it be backing up the injectors? just a thought i guess

Further toward explaining Rob’s symptoms. We know the Mag is flowing a huge amount of air into that engine however the power level is not where I would expect it. Since it has been proven that the intake valves open by boost pressure alone at pressures greater then 18 to 20 psi by myself and Master-of-Pain it is very possible a considerable amount of the intake charge is never used by the engine to make power but instead is burnt in the exhaust. Rob has complained that the Mag does not make power with NOS is also explained. The NOS is flowing right out the engine without making power by 23 psi opening the intake valves during the exhaust cycle. The intake valves together with weak springs could be acting as 8 waste gates.
So inadequate non-matched injectors and not upgrade the springs to stronger aftermarket ones explains a lot.

I have been going through this post and have taken in alot of info.
I have a MP and was not happy with it at first.
I have an 04 this was my first set up
Stock Block,Heads,Cams,and Springs
Kooks Headers
Magnapacks with xpipe
Accufab SBTB
50lb injectors
JLP CAI
4lb lower
2.7 upper
TR6
SCT 9100 tuner
That returned the following
439hp 515tq at 16 degrees
453hp 535tq at 20 degrees
truck had nothing at the bottom
went to Sal for a retune had then following done since the last tune. MP idler bracket,SCT Big Air MAF,and 6lb lower.
My returns were as followed
465hp 570tq at 16 degrees
474hp 571tq at 20 degrees
So what I learned from my truck is
YES you need to spin the MP.
But I only picked up 9hp and 1tq on my race tune(why even bother )
I see 17lb of boost then it climbs to about 20 21 at shift.
I waiting to see what effect the springs have on Robs truck.
One thing I would like to say is
Every truck is different no matter how you look at it they may looks the same and came off the same assembly line they are still different.
What works for one truck as we see won't work for another.

I find your satement about being offended, disrespectful and offensive. It comes off as "How Dare You Question The Great Sal".
The plasma booster did not cause burnt plugs. I ran a plasma booster for 2 years in every condition imaginable, including conditions much more extreme than you are dealing with here.
Now the 50# injectors not flowing properely would cause roasted plugs and lean situations.
My observation of this situation is that Rob wants to make more power than his credit card can handle. So he is mixing and matching components to save money. The ported eaton will allow tuning for the crap accessories he has chosen. But up the anti with a bigger blower and you cross another line.
This post started out as how the MP blower was sub-par to a ported eaton. This is simply not true. The MP put out more boost in your own tests. You could not convert it to HP.....don't blame the blower folks, it is doing it's job.
Have Rob open the check book and bUy MATCHING 60# INJECTORS. Go ahead and tell him what everyone else knows about the extender......BS and bitch to tune for. Buy the SCT Big Air...actually get the injectors at the same time so they all are set up to work together. Whip out the SCT software and get that tune where it needs to be for the MP blower. Then he will see what 3 extra pounds of boost will do for him.
All In My Humble Opinion.....no disrespect intended. I am just trying to get people to think of other parameters that affect power gains with new blowers.

Basically your saying Sal don't know WTF he is doing.......... In reality he has done everything possible with what he has to work with
It's pretty sad that the chearleaders keep pointing fingers at the person doing the tuning instead of the part(MP) that is being pushed by there favorite vendor..............
