There will be no need for additonal tuning. I would highly suggest having the stock tune before installing the kit. Tuning involves keeping the air fuel ratio correct and and keeping the MAF sensor in check. This has been factored into the kit price. I highly doubt the elbow from the MAF sensor to the throttle body will still be on the car after kit installation. I believe the charge pipe will be similar to a Needswings intake and eliminate the elbow.
