Hey Terry is it possible to get a update of the Pump flash to make the AFR less lean before 3k rpm ?

If i floor it in 3rd gear before 3200 rpm my afr goes to 16-17 all the time and then gets back to 12-13 after that....

id like to have a bef dialed so i can floor it before 3.2k and not worry about going super lean and causing detonation to potentially blow my lovely n55 engine

anyone has experience this ?
