Its a Digi 1 and Lamba capable Digi 2 think (not sure about that last one). When you floor it, there is delay between 1 and 4 seconds before full throttle enrichment happens. So you can end up at 5k or 6k RPM going leaner than you need before you get full power. I've read in some places that it was possibly done for scavenging the carbon canister although I'm not sure if that the exact reason. @easydaz which version are you interested in, something like SNS?
