What to expect from a tuner?
I have a new (95) PSD with 118K miles on it. It is in good shape and so far after 2 tanks I am getting 17-18 mpgs half hwy and half around town. I talked to a guy (salesman) about the superchip and he said he gets 22+ in his 99 7.3L on the highway. Is this realistic and what do you guys experience with the chips? I'm not a hard driver and I don't need the performance but better MPG's might pay off.
