We have some really weird proble.... The car is Mustang GT 5.0L Superchaged with KenneBell stage 2, it was Automatic trans, we put Manual. All tune data we manualy copied to new manual PCM. Everything worked fine, but sometimes we getting really strange issue, sometimes everything is ok. So, when we put the Full Throttle pedal - if evertything is ok - we have good boost about 15psi all the way till red line. If this problem occur - there is no any boost at all - and according to our log file (please see pic below) we have strange ignition retard -10 deg all the way with flored pedal. We can not understood if it could be some Ignition cut may be??? or may be it could be some mechanick problem (but in this case ignition shouldnt be - 10 deg).
If anybody may be seen some similar problem - please advise what can we check here to find the problem...
