XPR has a really good setting for the 350. I can’t recommend them enough!!

Would definitely recommend XPR.
Twisted maps on our Husky 350 are amazing. MXA tested it and Josh Mosiman said "this thing is a rocket ship! almost as fast as my 450". The only engine mods are the Twisted mapped Vortex and an Akrapovic pipe. I especially like the power map with less engine breaking, but there are 10 to choose from.
I forgot to mention it's already mapped by XPR for a KX so I think I might send it there maybe less issues I don't know. I would assume twisted can remap it also I guess I'll email him and find out

I have the twisted map in my ‘22 350. From what I’m told they picked up around 6hp from the mid range up. It for sure changed the bike. The bottom end was definitely improved also. It even sounds different across the whole rpm range.
As for who to go with, how many teams do you see run twisted stuff vs. XPR?
I also have a vortex mapped by Jamie, but how many Twisted engines have you seen blow up in the last few years..
I've seen this sort of statement around here a few times now, but I don't think it's really relevant for a couple of reasons:
1) Pro teams are pushing the 250's as hard as they can as power is everything. In a case like that, you'll get some failures no matter who built the engine. We saw a Honda factory engine blow up last season; that doesn't mean that Honda factory engines are no good. Twisted has a ton of engines out there; I'd bet far more than XPR. So naturally, you're going to see more Twisted engines blow up than XPR for that reason alone. I can say that no Luxon engines have ever blown up. But there are no Luxon engines out there to blow up either!
2) Typically Twisted builds the engines and the teams are responsible for upkeep. So if it blows up, it's not necessarily Twisted's fault.
I've heard good things about XPR too, but Twisted seems to be the standard and Jamie is a good dude who really knows his stuff. That's why we went with him on our project bike and it's been awesome. OP probably won't go wrong with either builder, really.
Do more teams run xpr ? I never really paid attention. I'm just a slow vet anyway
Well it’s not just 250 engines built by twisted that are blowing up. Brayton’s muc off honda locked up in sx, Hartranft’s recent crash I’m sure everyones heard of recently, plus all their 250’s on top of that. Sure he’s got a lot of engines on the track but 9 times out of 10 it’s his engines blowing up causing injuries to riders
But were those failures a fault of Twisted's work? There are a lot of reasons why an engine might blow up, it's not always the engine builder's fault. It's easy to point the blame at Twisted as they've got a lot of engines out there and there's no other information to go on, but it's all just speculation unless you know some insider details of the failures.
And Jamie isn’t maintaining them. He does the initial build then it’s in the team to do maintenance.
Correlation is not always causation.
I’ve had em both and both were awesome. Chad from xpr I’d say is a bit easier to get get a hold of and get answers from. I’ve lost count of how many guys I’ve let try my xpr vortex on their 350 only to have em come back in aw of the improvement over all aspects of the bike.
I’ve run Twisted mod engines and ECU since 2017. Never had an issue. They did a KTM 250 mod engine that was bullet proof.
My 2019 350 went over 130hrs on a Twisted Vortex before I sold it. Never even checked the valves. It’s still a great bike as my friend rides it.
XPR did a Honda 250 Mod bike that was amazing! ECU and all.
So as far as which company to go to? Call them both and see who you feel more comfortable with. You can’t go wrong. Both guys(Jamie and Chad) are on another level with ECU tuning. They’ve been at this for a long time and way ahead of their time!
^^^ Nailed it!
Kris Keefer did two podcasts with both engine builders, both great guys.
I have a TD ignition in my son's bike and a friend has an XPR ignition in same bike. Both are fantastic, can't go wrong with either. But I have to kind of feel like Jamie is getting spread a little thin with everything he has his hands in, Chad from XPR is definitely easier to get a hold of and talk directly too. If that mattered to someone.
I'll probably go with with XPR as it has a map from them for a KX now . I'm going wait until after holidays so it doesn't get lost in the mail lol
I can vouch for DynoDan on his recommendation for XPR (i might have said vortex on my 21 350) it’s a rocket and total game changer for the 350! Not saying anything wrong with TD but my XPR vortex is awesome!
Pit Row
Thanks for the input I'll go there . Should be more than adequate for my slow ass
New PulpMX pod with Jamie from Twisted;
”We talk to Twisted Development's Jamie Ellis about his motor building business, some tips and tricks for people, getting HP out of a motor, some motor failures recently and more. ”

I have had Twisted map multiple vortex’s. I have never had an issue. All my bikes rip with Jamie’s mapping.
As far as these engines blowing up, like stated, he builds the initial motor and it’s up to teams to maintain. It is possible that engines are not getting maintained at the proper maintenance intervals. This could be for several reasons. Maybe a smaller team needs to stretch parts a little further due to budget? Parts haven’t been the easiest to get a hold of especially in peak covid times. Some companies have had to outsource materials from different manufacturers than normal and that could have compromised parts. There are a lot of factors, and it’s not just one engine builder that has engine failures.
We have worked with XPR on 7 KTM/GG/Husq bikes over the last 3 years, they are great and you can actually speak to the guy who designed the maps. We had an issue with a different fuel spec and they were able to help us solve the problem.
Where are you located? I found the twisted is not suited for me..I live in the north east. Different climate
I agree with you jbrown. Jamie is spread to thin, not as available as he once was, including not even being around. I'll be going to Chad at XPR from now on.
I'm in Chicago. I sent it out to XPR yesterday.
Next time or if you wanna try different mapping check out Tom zont racing for your motor work their local up in lake in the hills IL and do great work. You can bring your bike up there and they will dyno tune your vortex ignition for your bike.
TZR did my KTM 350 and improved it. I may go with them on my CRF450R a bit later.
