I have a 2014 435convertible with the M Sports package and the M Performance exhaust
I am looking at installing a MPPK which off course is done via my BMW dealer, in Canada this will cost me $1973. CND plus taxes, they installation is free

I went ny another BMW dealer who is an authorized Dinan Dealer and can install a Dinan Tuner for $1000.00 more

The MPPK will give me 35HP and 32 Pounds Torque extra while as per the BMW Dinan dealer I will get 65 HP and 92 Pounds Torque extra............I don't know if these numbers are realistic and don't if I want to have a Dinan tune on my vehicle vs a MPPK when it comes to reselling

Need some advise

Thank You

I don't know about MPPK, but Dinan is realistic and one of the few acknowledged reselling gains for modifications in the US. PS You will be hard pressed to notice a 35 hp gain.

This won't affect the warranty?
