I am looking to get an upgraded chip/eprom for mty m42. I have read good things about the mark d chip but wondering what others are running.
I am really looking for that extra rev limit.
Also with a different chip has anyone seen a change in econ? Other than pushing it harder now.
This car is my DD and I really like the fact I can get 33+ mpg on the highway....and if I baby it around town 25ish
But I also autocross the car and would like a little extra from it.
tia,
