Have been reading/considering mods for my '19 Husqvarna FC350 for a couple of months. Put around 25 hours on the bike with no changes. The recipe that many have followed with good success was an exhaust, Vortex or remapped stock, intake changes (2-stroke filter cage, 2018 airboot, and vented airbox cover).
Sounds like a good strategy except I'm a cheapskate and didn't want to spend a grand or more with an unknown outcome. Lucked out and found a Vortex mapped for a 350 by Chad at XPR on eBay for a steal. Decided to pull the trigger on that knowing even if I had to have Twisted or another outfit remap I'd come out less than new.
Installed and did test ride near the house. Definitely felt different: light, snappy, revvy.
Two track days now and I can say I'd gladly spend the full asking price for a new one with a remap (XPR and Twisted both have good reviews).
My main impressions:
Reduced engine braking: more like a 2 stroke and had to return to using brakes
Throttle response: Hard to describe how much more responsive it is: barky, crisp, punchy, etc. Like a well jetted 2-stroke.
More torque at lower RPM and lower throttle openings: more like a 450 than before, but not overpowering like a hooked up 450.
Pulls harder in midrange: where before needed to really rev it out to get power. This bridges the gap (for me) between a 250 2-stroke and a 450.
XPR dyno'd an 8 HP and 5.5 ft-lb torque increase on their 350. Not sure about my particular bike and numbers, but my SOTP dyno agrees with the curve they show on IG. MUCH meatier midrange.

So, if you're on the fence about a Vortex, I would advise jumping over. The 350 is almost perfect now.
ETA: the only other mods I have is the vented airbox cover and stock exhaust with conical baffle removed.

The Shop
Just like jetting on many bikes
Here’s a video from Twisted about the tuning
Coming off a 2017 YZ250F with no map selector switch. The Vortex made a world of difference on that bike.
I'm super impressed with the ignition so far, the engine braking is massively reduced, I had a remapped stock ecu and the vortex works insanely good so far.
When I did my Vortex with them I didn’t want TC so they gave me a variation of another map.
Yes I think launch mode is gone.
Pit Row
If so -8602350116
I'd try that before spending money on an exhaust.
Not interested in selling my ECU, but there may be some on ebay.
Akra slip on (runs good w/insert)
Two stroke cage
KTM vented air box cover
KTM map switch to run map 2
I would love to loose some of the engine breaking as I still ride a KTM250SX.
An alternate might be to try 48 or 49 and moving everything down a gear: more second and third, less use of third and fourth.
