I have the 91 tune from nelson and i was thinking about getting a tune for some good gas mileage. Is there alot of loss of power by doing that. What kind of gas gains would I see? I was just seeing if it was worth doing it

 

anybody have the tune for gas mileage? just wondering if it really saves you gas

 

call and ask allen if yours has the dual tune on it. if so you should be getting ok milage even if you are using reg gas.

 

If it's a free re-tune I say go for it. If it costs $ how long will it take to start paying for itself?
