Has any one checked Gas milage stock then put the ECP kit on and checked it again, and what was your result's, would like the kit but don'want to loose much milage.

MORE GAS=MORE HP= Less gas milage...
You gotta give to get !!!
Its how it works.. If ya wana play you gotta pay!!
the more mods you do to your sled the worse the gas milage gets!!
But the faster the sled gets

You add mods to make your sled faster right??
THere fore you ride your sled faster right?? using more throttle!!
So you therefore use more gas right??becuase no one adds mods to there sled and doesnt use em!!

Unfortunately when people do modifications, they find themselves wanting to use the new found power and don't ride their sled anywhere near how they used to before the mods.
Once you turn into a HP junkie, it becomes difficult to not use the great running cjharacteristics that the mods now provide so it would be difficult at best to trust anyones testing for something like this.
I have however staed before with our air kit...Prior to the kit, you used to have to let's say use 3/4 throttle open position to maintain 70 MPH on flat well groomed ground. After the mod, you find yourself using 3/8 throttle open position to go the same speed. You tell me what would happen.
Also, think of this...with the stock airbox, the torque curve is so incredibly ugly that the clutches are constantly up and back shifting throught the entire curve even at one steady throttle setting. This must kill the efficiency of the sled, engine and drivetrain. I would like to think that because we greatly improve the torque line and that your clutches are torque reactive, then the engine has to work a lot less harder to keep a higher level of power to reah your track. If what I state here seems agreeable to to you, then think about how much you also save in belt, clutch and clutch component wear and tear because the clutches are now working a lot less. I would be willing to bet there is an approximate 1 to 1 trade off ratio despite the fact that we use a larger main jet when all things are considered.
Just some thoughts.

I too would like to know this. Adding mods does not always mean less mileage if the mod causes the engine to run more effecient like a good exhaust or a well tuned carb on a car. Makes more power with beter milage. I would like to know some real numbers from someone that has some actual miles on their sled not from some one that has 60 miles on it in the back yard and thinks its the fastest and it rides the best because someone told him it was.

Noone wants to let the facts out! Must not be very good!
Freddie we want facts not B.S.!!!

One of my buddies has the kit & has stated that he has experienced a fuel mileage increase of 1+mpg.

As much as I have been giving Super tuner manure about going to 165 mains I must say I am SO FAR pleasantly surprised with the economy I am getting with the 160 mains and the needles moved to one click richer than stock. Here's the results from an actual fuel slip comparison between my RX-1M and my wife's Phazer 500.
My gear head brother in law was riding my wife's 99 Phazer 500. It has a 121 x 1/3/8" full block track, hiperfax, SRX skis, carbon fiber reeds,energy release, blue marble oil,ect. He went 87 miles and the sled took 8.7 gallons of fuel to fill the sled to the upper lip for 10 mpg. I had just added a steeper heilx and more weight to the primary to get the shift speed back down from 7,800 to 7,250 where it's supposed to be.
The total gas bill is 15.180 gallons. So my RX-1 took 6.48 gallons and I went 93 miles (because I was running up and down the airstrip at WOT so many times) for a mileage figure of 14.35 mpg. This is with a 151 x 2 1/4" finger track with about 6 hill climbs added into the mix. I was not babying the sled by any means either. We're talking a good portion of the time I was at or approaching triple digits. My brother in law couldn't believe that my sled took less fuel than the miserly Phazer. I think he could have used a hose clamp on the throttle because he had it wide open all the time trying (by failing miserably) to keep up.
Yes, another needle taper would be fun to try because the stock needle transition area is SO steep that any change in needle position will yield big differences in just one adjustment notch. PB

Mine has gotten better.
ECP milage comparison
Most K+N filter applications will list a 10-15% fuel milage increase

Technically speaking it should improve gas milage if you are no harder on the throttle then before!!
But in the real world like supertuner said, You become a HP junkie and start blasting the throttle out of the corners and on the lakes!!USing more fuel!!
Eather way you look at it is a Good traid off!!

I think the Heavy Hitters helped my economy too. Why? Because before with my Daltons or 8DN weights I was turning 8,000 plus RPM just cruising down the trail at 55 mph. Now with the Heavy Hitters loaded heavily in the center hole (midrange) I can goose the throttle get up to say 70 and back off the throttle and I can stay at the same 55 mph and be just under 7,000 rpm. The clutches will stay shifted out at lower speeds (perhaps to the detriment of the backshift?) but the power always seems to be on tap. PB
