Just got an Edge evoloution CTS was wondering what boost pressure was normal running at 70-75 the highest it has logged is 22 when i gunned it on the off ramp but it mostly never goes over 4-5 . Also It keeps telling me im Avg. 36 mpg so i know that's b.s.... haven't loaded any thing over Econ and havent went through a tank of fuel to be able to hand calc. yet. I have it blocked and stuck and was wondering if the finger stick might screw with it. If any one has had any experience with one any insights would be helpful

Your boost pressures are normal. Don't ever listen to the computer when calculating mpg

 

yea i just need to run a tank through it to get actual mileage the DIC is damn close most of the time. also having problems with the air bag light and the keyless entry just stopped working and no, its not a battery or resync'ing just quit the other day.... any takers?
