Just bought an echo 620p after roughly 40 years of running about every model husky has had except the biggest model. Not wanting the expensive autotunes I decided to save roughly 300$ and try something else. I do still have my 346xp that I muffler modded and got rid of the limiter caps. That alone really woke that saw up. 13years and still runs awesome. Just wondering if my 620p would respond the same by just opening up the bottom side of the muffler deflecter and getting rid of the limiting caps. Really don't want to do any more. Thoughts or experiences would be greatly appreciated.
