Installed a set of Power Duals and Monster oval tuned with the Fp3. Sounds great but now around 60 mph with steady rpm's it sputters occasionally and has kicked off the cruise if I have it on. Stock AC.

Any help or advise would be appreciated.

Thanks,

Ryan

I would reinstall the tune, and make sure all your exhaust connections are tight.

Did you do a AC as well?

Thanks for the advice. I flashed the tune twice and checked all the connections. Should have been a little more descriptive. In 6th gear around 60 mph there is an occasional "lug". The best way I can describe it would be to say that it is similar to slowing down under 50 in 6th gear and the transmission jerks until you downshift but this is not as jerky as not downshifting.

Thanks

60 mph in 6th gear is the minimum speed for 6th gear, that's probably why it's lugging.

Only issue I had was that it didn't do it before I put the head pipes and tune in unless it was around 50. But I have been letting it run at higher rpm's since and haven't had any issues. Thanks for the info.
