More or less stock VVT engine (swapped in via the "definitive guide"), REV built MS3 Basic. I finally got the car mostly road tuned. I've done nearly nothing with the ignition or AFR Target maps, since most people say REV provides a nearly finished product.


Most/all of the tuning has been hitting as many cells as I can on the fuel map. Autotune, then some manual smoothing, although I still seem quite lumpy, especially on the higher RPM areas. No knock, smooth delivery, etc. Just curious what MT has to say about it. How much lumpiness is too much?

EDIT: 93 octane
