Hey guys I was hoping for some help.I have an 87 turbo regal that runs and holds boost perfectly,but only for the first 20 minuets of operation on cold starts,after that popping,KR,and service engine light fluttering when I go WOT.I have 42 lb.injectors,adjustable fuel pressure reg.hot wire kit and fuel pump upgrade,ls1 maf sensor & translator, turbo tweak chip,stock turbo,160 degree thermostat, scan master and a power logger.I do not have any trouble codes,and all numbers seem to be in range.After the car is driven for about 30 min.I am not able to go WOT without problems.Fuel pressure checks out pound for pound under boost.Any ideas on what is heating up causing this malfunction?If I leave the car sit overnight it runs like the monster these cars are, burn outs in second gear,but after 30 minuets of driving troubles occur.Thanks in advance.
