Trouble Codes on MAFia?

[Swiss-Stang]

Can the MAFia LED send out an trouble code? I still have the problem with my Mustang GT with a Procharger on it. No power and sputtering from around 4'000 rpm and a very lean AFR. Got a correct custom tune from your CMR Dealer in Germany JCD Cars for my application. He recommend to install the dual fuel pump from the shelby models. But no changes. My last concern is the MAFia. On setting 0 i have a better AFR but still no power. Can I got a defect unit? Should the LED inside the housing blink 7 or 8 times when ignition is on or is this an error code? Does it make sense to install a new one?

Help is more than welcome!

Thanks
Bruno

They will give a quick flash then 8 blinks on startup, that is normal.
