how to know if my car is tuned ok i am new to the ls1s and fuel injection usually had old cars with carbs. but just wondering how would i be able to tell if my car has been tuned, it has long tube header and y pipe(bought it with them) and no cats, there is no check engine light on and no codes present, any helpful hints before going and paying for a tune
