My torque peak is lower, but I still wouldn't get the best gas mileage at 3200rpms. In fact, I'd have to be holding 90-95mph to travel at 3200rpms. Now if only that gave me 30mpg

Aint that the truth...lol

As I get towards 80-85 my milage slowly drops... 80 seems to yield 29-30

Pete I have had my mixed driving as good as 27, and as bad as 19( I have no idea why

)

I do like to set the cruise at 75-76 and just let the car go... My last trip pulled 31-32... when I had the NGKTR55 plugs in there I managed 32-33... I have no idea what the diffrences were and what conditions were diffrent... Also when I did the 32-33 I ran nothing but 93 octane from florida to WV...( Yes I know the car will do fine off 87 as its non SC )

I do think that if everyone cruised at 70 like the signs say most all 3800 II'* would pull down 30-33.... But how many of us do 70 all of the time?
