Since You are in contact with Adam @HPS...we need a cook for the Dyno Day GTG April 15th..And Since Adam is Great at COOKING NUMBERS...ask him if he will stop over and Cook up some Burgers !
Update on the Jesse software program?

LATEST UPDATE: AMGSC car
Just spoke to MechTech. Still tuning the car but...
1) Boost is back up to 7.5 psi.
2) AFR remains at 11.5/1 throughout entire RPM band.
However they are now reprogramming the transmission control portion of the ECU so that the car does not automatically shift gears when the extra power is loaded onto the tranny.
Jim is excited about what's going to happen next! I asked him if there are any risks to my tranny or engine and he assured me no. He told me that the he feels that once the tranny shifting issue is taken care of. I should easily see 430-450rwhp.
I will keep all of you posted but so far so good!

Kleeman SC without ECU - S1 Package
Has anyone purchased the Kleemann SC without the ECU upgrade (+$1,000).
How does Kleemann make the power without ECU reprogramming either.
Everybody says it's impossible for HPS to get power without ECU reprogramming but nobody has questioned Kleeman's non-ECU package ($11,000). Does the non-ECU SC package with the stock injectors put out the advertised power?
Can anyone show me their dyno with the non-ECU (S1) SC?

But the boost did jump from 6 lbs to 7.5 lbs psi which maxed out the 37lb injectors.

I don't understand why you would need to adjust the tranny for more power. Seems like things are getting way too complicated.
I bet your car would make more power with the MP112 blower, stock injectors, Spilt Second timming adjustment, and a Super FMU tunned on the dyno.
I often wonder if the aftercooler is the problem in your system. It looks very small and restrictive, it may be reducing the air flow into the motor. This month I should be able to get 380whp once I add the chemical cooler.

I'm hoping for the best though 
and it better be well over 380-400rwhp on your 5.4 liter it should be more like 450+++ w/all these great new mods :

Not much you can upgrade on the intercooler core without having to redesign the manifold plenum.

Thanks for the advice about the heat exchanger and intercoolers.
Linh was present during today's dyno and said it looked like the rpm was fluctuating wildly during the dyno. Do you know how to disengage the ESP, ABS COMPLETELY so that the computer doesn't try to compensate for the imbalance by locking up the wheels even with ESP off?

If you want to try and attain 413rwhp albeit unreliably, then I just hope your engine doesn't blow up.

I recall Jim had the same issue when my car was on the dyno, however my car did not have the "dyno mode" feature, does your? I have heard in "dyno mode" the ESP is less intrusive but not competely turned off.
-Turn the key to the second position
-Quickly press the R button (Odometer reset) three times.
-You should be able to see this screen that displays voltage -Scroll with the up/down arrows until to see the screen that shows the toggle options for dyno mode
-Use + or - to toggle
Good luck Rob, I wish I had your patience.
Really...the HE cracked or the intercooler core?

Something else is going on with the tranny, it should hold 600 HP plus.
Car should dyno by simply turning ESP button off. Again something else is wrong with the setup, DME does not like it.
