Fuel mileage with new injectors


Recommended Posts

Got my ducky 7x9's in the other weekend. Working on my tunes a little at a time.  Seems as tho my fuel mileage has fell pretty bad. Now that I think about could my mileage have reset when I unhooked my batteries??? Anywho the lie o meter seems to think it's not to much worse than it was. I have finally made my self stop getting on it every time I get in the truck! I have put about 300 miles on it since putting um in so I don't have a lot of data on um. However I can cruise at about 65 and timing is 18.56ish. Egts are at around 660. Add more timing or just give it some time for me to adjust to the new power?  Mainly will the odometer reset with batteries unplugged. That will answer a lot of my questions as of now lol

I could be wrong, but Ducky's are pretty good injectors. It's the DDP's that are junkers. I'm sure we'll get clarification.

You absolutely could be right on that. Now if we could just get @Me78569off his porch he could enlighten us. I have not had enough crow to eat today.

If you unhook batteries I’m pretty sure it resets trip meter

That is correct. I didn't think so but I found out during the ground mod that the trip does reset after disconnecting the batteries.
