I didn't get a chance to push the car to the higher rpm range as most of my testing was in the 3-5K range. The clutch engagement from a standstill did improve, which happens to be a concern for us F1 duo QP owners. I suspect the DBW performs better at or close to redline just like it does without. Over all there are improvements all around. Not sure when Ill get my issues resolved but looking forward to redline testing.This is actually really good to know. I did a comprehensive review of the early 2005 and the late 2007 Sport GT, back to back, last year. I drove them to their limits and tested every shifting attribute. The weak side of the 2005 was the delay from the paddle signal to the actual shift. They improved on that in the 2007s, but I didn't like other improvements that were made, like the double-clutching, higher downshift revs, etc. The 2005s needed more throttle feathering to bite on slow takeoffs, so I'm wondering how the DBW install affects that on the older cars.The engagement time between gears speeds up, however the response time from the point you pull the paddle to the time the gear starts its cycle feels the same. Currently removed the DBW for troubleshooting. Will reach out to FD today to solve my discrepancy.
Other comparisons I made were with regard to suspension, which again there were pros and cons of each.
