I have a 1998 Toyota Camry XLE V6 AT that I have been trying to hypermile. I just got a scnaguageII as has been recommended by many. It seems to have helped a bit as my MPG with the sensor on has been about 35 mpg on this most recent tank. However, one thing I find odd is TPS is at 14 when I am at idle or neutral. Yet, when I've got the vehicle going about 50 mph, it seems to only be at 18. It also seems just about impossible to get it up over 60 - I have to floor it and near redline it to get up that high. Is this feature reading correctly or does that sound reasonable to those of you who have more experience using the system.
