2Bros Exhaust with their ECM..Backfiring

Notice yesterday while riding, when I would slow down, it would pre-detonate, basically back fire on me, haven't touch their presets and notice they're most of the time in the green zone. It's more noticeable in low gear and slow speed. Have the VALE exhaust with their ECM also the Uni filter with a twist throttle.

Has anybody else seen this issue?

Thanks

Well when I was running both of those I would ease off on the throttle to kinda slow down and take off some rpms and it would fall flat on its face and then I would punch it and it would spit and sputter then backfire and work good until I would try it again. I tried everything then I got pissed and bought that PC3 and its been fine.

Can you tell what are the settings you have, it might be that you are lean in the 1st pot, try richening 1st pot a couple of clicks.

It's factory setup which is usually runs in the green mode which should be ok but I can try to adjust it this weekend if I ride.

Yeah, try to set each pot how the optimizer instructions tell you for idle, mid and wide open throttle. Should make things better. Other than that make sure that the boots are ok and that there is no exhaust leak as well.

I've had no problems like that with my 2bros and juice box, and I'm using the factory settings and UNI filter.

get a PCIII or V and you wont have any more problems. I finally got rid of the "junkbox" a few weeks ago.
