I have 45mm open Termis on my 748 and a guy on here sorted me a Ducati chip matched to the exhaust for £15, the bike had a chip change when I bought it but I could not find out what spec the chip was so decided to err on the safe side.
The difference with the Duc chip is amazing, crisper, faster response, and also louder. My assumption now is that the original chip was incorrect for the exhaust set up.
