M30B35 1992 E32 735iL tuning

[fangioe36]

Hello,
I am having soon installed a DINAN ECU upgrade for my E32 735iL.
I already bought it and it will be installed by a DINAN dealer. This upgrade would bring the max rpm to 6250 from 5700 with a max power output of +40 HP if I remember well.
Did anybody tried this upgrade ? Is it reliable and recommended ?
Thanks a lot.

So the DINAN chip tuning feels really good, for sure really more torque and I Can feel it. For the HP gain you have to go above 5000rpm up to 6250rpm.
