Stock Muffler Tune

[ryama]

I have 1500 miles on the Evo stage 1 tune. Very happy

Could you tell me if the tune effected your fuel milage much?

 

[lakercr]

I've gone from a 1.95 to 1.85 gear ratio with the Evo stage 1 tune. Rode 97 miles last weekend after filling up and still had over 1/4 tank left. I have no complaints on the mileage.
The sled pulls harder in the mid, and is about 10 MPH faster now (6-8MH with just the tune). I've done many long pulls with my setup, and it has been flawless.
Out yesterday for a ride and did a few WOT pulls. 120MPH GPS in heavy wet snow (temps were +6c/43F. Engine was always between 164-177F.

Pretty much stayed the same.
I average between 12.5 and 15mpg depending on how aggressive I ride.

I am quite envious of your power and mileage. Glad to hear about that nice combination.

Thanks--already have the TPI kit, so EVO stage ! tune should be the ticket
What is your target shift RPM? Gear Change for 1.85 ratio?
tx

 

[lakercr]

Shift at around 8800, and then RPM climb a few hundred on WOT. 22/41 = 1.86

This is what it looks like:

[lakercr]

Me too - bigly. Lot of people are saying that less dog leg is good, I can tell you that.

I've got to stop watching CNN.

Yes, that's the cat 1702-395 22T gear. Chain is stock.
