need your help please i have an evo 10 gsr. my car is stock right now and i want to mod it .. so im thinking of putting an INJEN upper ic pipe and intake. is it ture that i have to flash and tune my car after i put those on??? thanks........

 

Look at Vishnu Performance. First thing I did with my Evo9. 29

 

yes u will need a tune, but u mite as well wait on the intake until u can do exhaust with it, intake, exhaust and tune is around 100whp on X's

 

get an exhaust

get a tune

done

seriously thats basically the way to extract 90% of the power available to you
