I bought a Stihl MS362 one year ago and have broken it in nicely with around 15 tanks through it. I love the weight and balance of the saw, but now want it to bring more power for its size. Is there anyone out there with a modded MS362 that would recommend a good porter/muffler modifier/tuner for this saw? I love the saw, but want a lot of power. I have a stock MS661, but want a more nimble powerful MS362. Thanks in advance.
