    You know what they say about assumption...... maybe it’s a stroker motor or maybe it’s?

    Latest front end

    Perfect, the race guys use what works! Yea but longer tracks and jacked up sleds look way cool! :drink: Besides if they didn’t make some changes what incentive would you have to buy new?

    Rear of sled severe sag...... Pls help

    I doubt the gas pressure has leaked out this quickly. A revalve won’t do anything for sag. The front track coil over is way way to soft for my setup. If you have studs and want to loosen up the rear end some you need a much heavier spring. I’m 170 lbs and the front track spring was to light for...

    Gap closed loop tuning!!

    I’m telling you it’s more for fuel differences than warmer/colder days. Don’t really care if Dave agrees or not, the fact is non ethanol, 10% ethanol and specific gravity differences in fuels will cause bigger afr changes than humidity, that’s a fact. Anytime your tune is off, considering...

    Gap closed loop tuning!!

    Does the GAP software allow for user settings for afr targets? Can you modify your base VE table for things like intakes and larger turbos? I’m thinking no, but I could be wrong.

    Gap closed loop tuning!!

    Oh I’m not arguing it’s a better mousetrap, just letting y’all know that air temperatures should not have an affect on afr of your engine if it’s properly tuned. E85 vehicle’s use a ethanol content sensor because once you get more than 15% alcohol content, oxygen sensor is to slow to react and...

    Gap closed loop tuning!!

    That said my Viper seems to go leaner during very cold temps, shitty factory tune is probably the real cause.

    Gap closed loop tuning!!

    Warmer weather or colder weather shouldn’t affect your afr’s, you have an intake air temp sensor that adjusts for that. If your sleds going pig rich in warmer temps, it’s probably because it’s tuned for that. When your engine gets over a certain temperature there’s more than likely a fuel...

    Ultimate Sidewinder Muffler Decibel Test

    Thats the facts. I tune vehicles quite often and have seen just an air filter change make over .5 afr difference in the tune. Start adding in different lengths and diameters of intake pipe and it gets even worse. Never changes the cruise area of the tune just the full throttle afr’s. Food for...

    HUmmmm.... well I would think once I’m out front it’s on you too get by me? If you think for one second I’m going to relinquish the lead because my points are all used up you best think again! :drink: PS. That wouldn’t require luck, it would require skills!

    Seat concepts/mountain seat

    Trail sled with mountain seat? Should handle like total garbage on the trails. Higher center of gravity is bad for cornering, tippy! I’ll never understand why guys put taller seats and bar risers on trail machines, I actually swapped out my 4” stock riser for a 2” and it’s an improvement in...

    Ultimate Sidewinder Muffler Decibel Test

    It’s not so much as to whether the incoming air is colder for one system to the next, the intake air temp sensor adjusts for that. It’s the amount of restriction the intake has compared to another intake that will make the biggest difference. Evidence here is, different intakes have different...
