I got mine a 03 150,000 miles 12-12 first tank 22.7 my last tank 27.8. Do check for brake drag, the gas pedal by wire does feel different.

Odds are its not the ECU. Change the plugs and PCV now and see what that gets you. Then clean the throttle body use good gas no ethanol that got me 4mpg more.

Last 2 tanks 25.5 so we might be on summer blend now.

They found me after owning for only two months. At least 3-6 owners I guess.

Got mine today.

Well last 2 tanks 24, 24.5 latest with 140 highway and 27.5 MPG . I think I am going to get 24 on winter blend we will see what summer blend gets me.

Temps have been all over the place 20-50 F. Tires 36psi, MAF cleaned second tank. Plugs were NGK IV, also have the auto so I think I have done almost all I can, the 420 is off more than on so far. I hope the new front O2 helps on this tank. Thanks for helping.

Greg

Well second tank was 24.6 MPG. Today I put in a O2 so I hope that was slow enuf to get me 2 more MPGs broke 1 rear bolt but it does not rattle yet. Its close to the firewall so is going to be hard to get out.

Greg

Well looks like central and woodlawn is lhe only one for good gas..

I am probably not right on this but is boost set to 14.7 for altitude at sea level? With all the changes I am making I'm sure how good my MPG readings are.

Greg

Wichita here, looking for MPG info. Q-trip gas is no ethanol right?. also any one using the torque app?

Greg

Did you just do all the standard info or did you adjust any of the extra fields?
Boost = 14.7
volumetric efficiency = 85
MPG trim = 1.0
ODB speed multiplier = 1.0

is this what you use and get 3% error.

Thanks much
Greg

Thanks, did a pcv valve today might help some more. I might need to test the CAT what way might be best a temp front to back test, or vacuum test. If it's a back pressure test might need to have that done. The 420 does go on and off, so might not to bad yet. Any one using Torque app ? any tips? Than...
