Hey guys, I’m relatively new to the ds450 community I just picked one up a couple weeks ago, it has the Motoworks full exhaust and pink wire mod and the air box removed, other than that the engine is stock. It pops and backfires like crazy so I was wondering what Fuel controller/fmi to get. I know you can’t get the motoworks fmi anymore so I would like to hear what you guys think. Thanks
