before this i boost .35 bar also no overheat,after installed individual bosch coils and lt10's now overheating(.35 bar also). wondering wats causing it. normal driving it doesnt go past 95 degree.but 95 still high for water temp.used to be 90 and below.once i boost,it climbs up pretty fast. and theres a small rattling sound in the engine bay.not sure... seems like the rattling sound n boost seems to cause the spike in water T. any other ideas as to wat couldve caused it?

sounds like pinging/knocking a bit to me....

maybe re-tune the ignition to retard a bit can help solve this... :adore:
