You have General info  Me7.5+Turbo+Gasoline  Cheesy What part of the General info is it that you dont understand? heheh. sorry..
If this wont solve it self the easy way i´ll logg later. I have to drive a long way to get to a good straight road.. Living in the center of the City.. I hate it. And if I run into problems no one can pick me up. Moving to the country side soon Smiley

Anyone else who have experienced the problem i describe? It just Cuts all power like "Snap" when accelerating on boost..

Would be a load better with logs, i reckon you could have found the problem by now with a log. KFLDHBN maybe?

Heres my KFLDHBN i´ll raise the last columns... Looks like they are abit low..  If thats maximum pressure I am boosting over that limit..  Im around 1.3 @ 5000 rpm..   Looks like LDRXN needs to be increades aswell. (Maximum specified LOAD)

HBN is max pressure ratio map, worth lifting it - but you'd be able to confirm that being the problem with logs.

Likely that KFMIOP and KFMIRL values may need raising to allow for your higher LDRXN

DHBN is tans and nmot, so unless you have some pretty high intake temperatures you don't need to touch it.
What turbo are you running?

Im runing a journal bearing Gt2860 T25 with some sort of  eBay tubular manifold 3" Downpipe. 630cc inj..  I have tested this with my old narrowband ECU and had zero problems with the IAT.. Its very coold outside here atm around 5 degrees.

I´ll raise that table and make some logs today. KFMIOP and KFMIRL are already tweaked.
