From what you said in your pm 85% for the injectors is to much nearer 60-65% would probably be closer the mark and you also need to set the lag time both settings are very important.
You shouldn't need to be backing off the timing that far either to get it to run right if you have the injector settings setup correctly it should run pretty much spot on on the std settings although the timing would need adjusting slightly as it will be setup for 100 ron fuel but only by a few degrees.
Tbh you'll be best off taking it to a tuner and getting them to set it up and map it as getting it wrong can be very costly
and (no offence ment
) you sound like you don't really have much knowledge with the power fc so shouldn't really be messing with it.
