Its a must for anyone with a boosted car period. leakes in the system will cause your car to run funny most of the time causeing a richening effect because the air from the turbos or supercharger isnt getting tho the engine. I installed some widebands so i can tell know when i have a leak somewhere because of that richening affect and the time it takes to boost up. I still do manual checks regularly especially after running it really hard.
