Need some advice please
About two weeks ago I was driving on the highway doing about 70 mph suddenly the car lost power. I was able to get it to my tuner, they are having a hard time finding the problem, the cats are good, the throttle body is good, 02 sensors are good, the tune files are all crazy and running very rich fowling the plugs. I have paxton 2200 s/c GT-500 fuel pump, DSS stroked 302. Any suggestions would be appreciated.
