Something isnt right there!!! Had mine dyno'd last week and made 459/448 at the wheel. Granted its a 6 liter with LT header, mini cats, magnaflow cat back and a smaller blower pulley. But its an automatic. I'd have it re-tuned somewhere else or you have some serious beat slippage. What did the boost curve look like?
My SSR: '03 RED vin1337, '06(lastoneinblack) vin 24107..Sadly sold '04UV,'05SILVER,'06PACBLU FPR
Something is definately wrong. I would call Magnacharger, and talk to a tech.
Also, I'd try another dyno run, it sounds like the program they put in is not correct. Although I never had my 05 dynoed, I can tell you that it added plenty more than 40hp. I see you have 4.56 gears. That may (not sure) PLAY A PART in the correct fuel curve/rpm ratio for the program (not sure)
I see on another thread you recieved a Superchips TUNER for the upgrade. This is different than when I installed mine. I sent my ECM in to let Magnason tune it. Maybe they sent you the wrong tuner.???
Can you post the curve sheet on here. Would like to read the numbers. Thanx
Achias: I agree with the others. Also this is kind of a trick question and answer. Your engine can only breath as much as it can expel...so better flowing heads/exhaust and an unrestricted intake system will net higher HP gains. Having said all that you should realize a minimum 100 HP increase.

Magnason clearly states 100+ rwhp on an otherwise stock engine.
I believe this to be true.
My SSR: 05 Black SSR. Magnacharger 2300, and then some.
I agree with all the others here. Something is not right with the dyno numbers.
I had the Magnacharger 2300 installed, and I certainly gained 100 HP. I had a cam, and exhaust done before, but it dyno'd at over 560RWHP, and tons of torque. You will know when you gain 100HP. Can you tell when you drive, as opposed to just looking at the dyno numbers?

The tune provided by MagnaCharger is based on testing with a completely stock vehicle. If you change other things like headers, exhaust, cam, gears or anything else performance related to the drivetrain then the tune is not set for that.
You have to get a custom tune for custom applications. The tune is CARB certified and can not be changed by MagnaCharger.

I started out in '07 with a 112 Maggie, a set of headers and a 3" exhaust and dyno'd 446 RWHP (thanks Joe!).
After the installation of an LEP cam and swapping out the 112 for a 122 HH blower (thanks to Joe Delano and Hank Wolf), it dyno'd 589 RWHP in October of '08, which is still warm in Phoenix.
Blowers love cold weather! Ask yourself if it sets you back in your seat, if it does, the dyno is irrelevant. I haven't driven Hellvis since May, because driving a blown SSR is no fun with 100+ weather.
I'll add that the initial tune in October left Hellvis flat after the initial dyno.....
Joe Delano attended the Laughlin Run in January of '09, and he spent some time tweaking the tune. By the time he and I had been cruising at 100MPH + for twenty minutes or so, Hellvis ran (and still does) like a raped ape!
The worse cause you will add 100 hp, My 5.3 with headers free flow cats 1.85 rockers and new valve springs dynoed almost 500 rwhp and got better mileage, Run 12.70 at the strip, Why did I very change it, I didn't use their tune
Although these dyno sheets do not include any boost numbers, maybe they can help tell what the problem is with my setup.
What is your interpretation?
Unfortunately that doesnt tell us much.
We would need to know the tuner, timing being used and a list of your mods.
I would look at a new tuner if that is all he can do with a dyno tune.

The tune was the standard SSR tune that came with the Magnacharger. The only hp mods (so far) are the true dual exhaust with Jones glasspacks, 5" tips, and no cats. We did take some of the rev and speed limiters off of the Maggie tune.
I have noticed that the blower whine that was there with the new install is gone now (sadly).

Do you know what your boost level is now?
Give me a call tomorrow and I will help go through some checks with you.

I have talked with Joe on the phone A LOT ! Asking him way TOO MANY questions about this and that when it come's time to install my "112" here in a couple of months on "BLACKIE" He has spent the time to answer EVERY question that I threw at him, in what I'm doing with my "rig." Joe has steered me in the right direction on what I NEED and DON'T for my installation.
He has even gone as far as steering me away from products that he sells, that are not needed for my installation! With this being said.... Tell's me just what kind of man is behind "32 LEFT COAST"..... A man you can TRUST!

So far, we've figured that the problem might be that the computer can't handle dealing with the lack of cats, even though the O2 sensors were turned off.
Partly for that, and partly because the exhaust is so loud that I'm concerned about neighbors and cops, I've ordered a set of Magnaflow high-flow cats. Once they are installed; I'll check the boost, then see if Magnacharger can help me out with a tune better suited to my R.
I'm really trying to avoid having to get a $500 tune on top of what the Maggie has already cost.

Correction: the problem was the aftermarket true dual exhaust. The cats didn't change anything except make me more comfortable around those who unfortunately lack an appreciation for the low, loud, throaty growl of a muscle truck.
The boost tested at 7 lbs, recently. It's supposed to be over 8, so we're changing the pulley and recalibrating the computer soon. Hopefully Ilsa will start putting out over 400 hp and get her whine back.
Imagine that - actually wanting to hear a lady whine!
