Here is my Report.
Downloaded my tunes Tuesday night. Have driven it 60+ miles a day from Wednesday until today. I loaded 4+/91 tune. Prior to that I used stage 4/91 on my SCT tuner for a few days.
I had driven with my stage 3/91 tune for a couple years or so. loved the firm shift and extra power.
Earlier this week I got the stage 4/91 for the SCT. More power, same shifting, firm. You know when it went into gear. This was right out of the box.
The last few days, have been using the Stage 4+ Mycal tune. Power/pull from idle to red line. Shifting? Meh. It loves to go into a higher gear, instead of staying in a higher RPM. When i get on it, it does not hesitate to downshift, but the shifting is far from what I would call firm. Even hard throttle from a standstill, does not seem to produce a firm shift like I had been using before. I drive my car pretty hard and fast where I can. It is not like I baby it.
So I guess I will try out the Stage 4 Mycal, and the back to Stage 4 SCT X3 tune. Overall, happy with the power, not so much with the shifting. Guess I will keep the SCT X3 tuner for now.
