There is a value askew that is not being met for that thing to run all out.
Revert to the old tune, do not ask for as much and do another pull.
What is your fuel pressure through the pull? Are the old pumps keeping up etc
What are your IAT's at 4500?
I mean at this point treat that thing like an airplane motor and add dual-wide band setup and left bank right bank EGT monitoring etc... dial that sucker in with a live IAT meter and keep rolling hard until it is time to sleeve and forge piston that puppy...
IAT's prolly IMHO spiking, or hotter days then when you pulled hard....?
IC pump not keeping up after the car has sat there heatsoaked the IC in staging lane or running on Dyno...?
Do you have an Ice Box or were you possibly pumping 90C water through the IC?
IATs kill these cars no matter how much power you try to throw at them...
Thinking out loud here...but without environmental and system variables clearly stated all that can be done is guess at this point.
Add info as you can tell I am thread stalking and would love to dig in more

Something is happening about 4500-4700 on your pulls.

i have a big heat exchanger, split cooling and 3 meth nozles
so no timing is being pulled
its the same tune, just thinks the tires rubbing the fender makes it skeved

60+ hp is one hell of a rub, others on drags have not had that effect
What does your Wideband O2 say through the pull? I bet that sucker is pig rich if the total you are spraying is more than a single 10 nozzle. 3 nozzles is overkill more than likely and jacking your AFR up...
If your information was water, this would certainly be a desert lol

Good find on the leak, honestly I was gonna suggest but didnt want to sound dumb bc its is most all aluminum
Was your leak between the throttle body and the transmission; the rubber coupler that connects the surge tanks to the supercharger output? Or Surge tank to intake gasket?

Hell yes! Looking graphs over I had to extract my foot out of my mouth as a picture is worth a 1000 words

uppdate!
car is working great
cold starts issues is solved, simply by turning ignition on/off beffore start
iff it is the 550cc injectors or loosing fuelpressure when sitts still dosent matter this procedure allways work
other than that i have been trying loots off different lenght belts for the sc
im not real pleased whith the log on the boost going upp and down 4-6 psi
its making it hard to tune and leaves power on the table
maybe its not possible to have a good nice boost curve whith the 72mm pulley?

So interested in this setup. I am needing a piggyback device so I can run a map for when meth is turned on. Have tuned my other car running meth and made a nice gain while temps stay low. Running meth on the M113K is notorious for actually loosing a bit of power untuned for it, but it will make that power all day long. I now want to tune for the meth and actually make proper power. Thanks for this thread, hope the OP is still around on this project.

On the DET3 another member said the timing retard ends up being 6 degrees of retard per 1 unit entered into the app. The timing advance is indeed 1 degrees per 1 unit. Can you confirm?
I need to advance and retard, and be able to adjust my closed loop AFR ratio with O2 sensor skewing. I wanted to know if the DET3 can do that?

Ecu help
hello everyone
first post
this weekend i wired in and mapped my e55-03
whith a ecumaster piggyback
my car iss curently running whith a 77mm fsp, 82mm tb, headers and no cats
3 meth nozzles mapped by pwm
before this whith my mail tune the car has allways been lean when on throttle from low rpm
took me literaly 5 minutes to map this out whth the piggy
runns so nice and strong now
and also whith a safe switch map when running out on meth
this is my daily driver now going thru a coold winter in sweden
