I put this on and my saw came to life. Had to do a little tuning but nothing major. If you are on the fence about getting one, well jump over and get it, You won't be disappointed.
5 min performance upgrade. You do need to retune after install but the cost of this upgrade is worth it. Buried a 36” bar in hard maple after install and couldn’t make the saw feel it. Unbelievably easy upgrade.
