Tune is never a bad idea but a pcIII is a must with the mid pipe mod. you will also most likely want to block and remove your AIS system.not to topic steal, but i got a Mid Pipe/GYTR Slip on coming along with a PCIII. Will i need a tune, or will the PCIII be sufficient.
Sorry 818, another slight topic stealer but im purchasing a carbon ackroporvic "slip-on" only rather than the full system, no one's mentioned whether you would need a pcIII with just a slip on or is that what you guys mean by mid pipe mod? Anyone Know?? as raven's mentioned does it mess with any of the sensors or cat converter??Whenever someone changes the restriction in an exhaust it changes the fuel mapping the engine needs to run right. Other things known as backpressure that is also read. The O2 sensor which is also needed for the fuel maping. The R6 comes with a catylatic convertor, if it is removed, pc3. If you remove the O2 sensor PC3. If you put a full exhaust on PC3. I don't believe any PC3 is set for a certain exhaust. Yes your bike will still run if it isn't tuned. Does it need tuned? If you want to get the full potential out of your bike, YES!
