after installation on my 390 she has backfire on decel and stalls once in a while do i need a remap ?
 
In general, those do sound like the symptoms you'd fix by rejetting or remapping :) ... wish I knew specifically about these bikes.

Incidentally - Which model year is it?
 
You've removed so much back pressure with the new system, it is now lean running. You'll need to add more fuel via a remap. If you were on the stock map, maybe try the competition map. If all else fails, add a jd/dynojet type tuner. It is super easy to use, it is a full piggyback system. it allows you to address fueling in 3 areas of the rpm range, as well as 3 other aspects of how fueling comes on/off.
 
Thanks Rensho

I called around to the local husaberg dealer they don't have any Husaberg maps only KTM
They are talking to Husaberg about that today , where else could I have this bike tuned ?
I live in Nova Scotia Canada , would I need to ship the computer out ? I ordered a trail tech mapping switch
Could that help out in the interim
 
Update

Dealer was able to get a map for a 390 from Husaberg with akropovic exhaust bike runs and pulls like a best
no backfire on decel and and no stalling , runs great in the technical stuff now

:bounce3: :bounce3:
 
Sweet!

Would you say it runs better in general now than when it was 100% stock, irrespective of the exhaust? If you can make that comparison.

Now you're no longer cursing that $1000 'upgrade' huh? :D So awesome.
 
The dealer and husaberg it should make 2-3 maybe 4 hp with that exhaust and header with the correct A/F
Map I know for a fact it runs much better smoother and not easy to stall in the tech still , also pulls the front wheel Much easier loving it all over again I'm retuning the map switch from trail tech when it arrives don't think i will need it :mrgreen: :mrgreen:

Never cursed the upgrade I knew the power was there just had to be unleashed
Not to mention I have the best wife she lets me buy what ever I want for this bike and my FE 550
Even goes as far as reminding me to order stuff I want

:cheers: :cheers:
