it is very weird we cannot get it rich enouh while everyone else runs at stock fuel system? either way we are running to lean. from about 5000rpm upwards
we have fuelpump and 650cc deatschwerks injectors waiting to go in now, but we worry about 1.35 bar on a stock engine (we just blew the stock headgaskets at 5000rpm) so i want to make sure 100% we have the right pulley or maybe our map sensor reads wrong
we have the following settings for the honda/denso map sensor in our oft:
multiplier: 0.367
offset: -0.045
this is a screenshot of a log we made, look at the fuel data and map reading.
any info on KW C30 pulley size or max boost please?

Just a thought if you using an OFT and Romraider definition from Github or OFT site those definitions are in Imperial ie psi not metric bar.
@
Kodename47 has done some metric definitions.
did you convert map sensor bar to psi ?
the OFT Vortech SC tune uses Omni 2.5 bar MAP sensor
the setting in that rom are
Multiplier (psi absolute/v) = 7.251
Offset = 1.450
Did increase MAF limit max (g/s) NA roms its 200 vortech SC rom 500
I know nothing about SC/Turbo tuning just some suggestions.
Also noticed on Techstream your Calculated engine load is 100% maybe your hitting a load limiter ??
