CM2350 factory file comparrisons...

[Scaner2]

Hi everybody,
I'm new on this forum, already found many interesting things about our trucks. Thank you everybody posting here interesting info.
I have an isx15 cm2350 on a Volvo truck with 700k miles on it. Bought it at 600k miles and not thinking too much about ratio what is 3.42 10 speed manual. Previous truck had 3.90 with 10 speed manual and was perfect for me. I'm not driving usualy more than 65m/h and with actual configuration have a problem... In 9th speed can go max 55m/h at 1600rpm an in 10th one at 1500rpm already 70m/h. This truck working local -regional no mountains and 55-65m/h speed what is usualy required is hard to cover with proper rpm range 1400-1650. If rise rpm more than 1700rpm i don't like engine sound, seems too much... Not ready now to invest in a 13 speed transmision or another diferentials with higher ratio. Thinking first to try maybe another calibration with diferent torque/rpm rate. Right now this engine have ef10053.47 cpl3937 with 450hp/1650rpm all systems in place(not demandated). I need an advice of what calibration else can be used for this engine. Thanks.
