The power gains without a tune vary from 5-10rwkw. However after a touch up tune to suit the rockers you'd be looking at around 12 to 15rwkw.No need for stronger push rods at this level in saying that if your increasing the rev limit and will be frequently reaching and staying at high rpm then it would be an upgrade to consider
