Hey guys Recently had my car tuned after an overboost issue, soon as the car came back from tune it started playing up, leaning out, making strange noises etc. She lasted about a week before she blew. Turns out the car was leaning out things heated up and bang! I was pretty disappointed. Anyways costly mistake on my part but I have a new motor and some 42lb injectors hopefully to stop the lean out, I was just curious if when I replace the stock injectors with the bosch 42lbs to stop the lean out will it need a retune or will the injectors do the job without computer tune? The car has a larger cooler, modified cold side intake and a tune running 249rwkw ANY info would be greatly appreciated!
