New here 2017 kodiak se

Update* so added .7mm shim and purple secondary, grizzly handle bars, hmf optimizer, qs exhaust, uni air filter. Couldn't stand the deceleration popping so I took the exhaust,air filter, and optimizer off. Still had deceleration popping with the stock exhaust but it was quieter. After riding for an while it cut off on me a few times when going from reverse to high, started right up. I had been reading a lot on hear about these bikes running lean so I put just the optimizer on it and played with the settings finally had it set at 2 1.5 1.5 and it run good no popping or cutting off for the first hour -hour and half then started popping again and cut off once at very slow speed got home and the header was glowing red, so I took the optimizer off and sent it to the dealer. They bumped the fuel up 25% on 1/4 throttle. It still has the popping and made it about 10miles and it cut off again. Dealer wants me to bring it back to add another 25% to it. Not sure when I'll be able to take it though they are about 1 1/2 hours away and I have to get up with my uncle to take it. He has the truck....
