Its still too early to see OV tuning results in the 3d gen skactiv 2.0, but people noticed a 10-15% increase from the tune on the 2nd gen with lower compression and old the 4-1 header. That is already greater than a 2-fold improvement compared to this Unichip, and one would expect more from the 3d gen 2.0 based on its compression and 4-2-1 header.Is the ov tune better on the 2.0? I'm interested but want to see results.
There are people currently getting their 3d gen Mazda 3 2.0s tuned. This started a few weeks ago:Very promising. Has there been any 2.0 tunes or is it strictly 2.5 for now? A smoother and more linear power curve would be nice
