Ok i have a 2005 IQ 440 and it was a sled on Tech Lab Racing. When i go into deep snow when i give it enough gas to hit the power band, it cuts it off and acts like it is running on one cylinder or like i fouled a plug. But when i get back into a packed trail or where the isnt any deep snow the sled is normal. Does the sled have a rev limiter on it? Could this even be the problem. Any ideas of how i could fix it. Or other suggestions of what it might be. Anything would be great cause i see all these videos on youtube off 440's just pulling up the skis in the deep snow and it makes me jelous.
