i have a 07.5 lmm that i put a dsp 5 tune on it runs great but after every cold start it goes into reduced power mode the reduced power mode is noticed shortly after you start driving it. All you have to do to reset it is turn the dsp 5 back to the stock tune for 10-15sec and it will run fine . After it resets you can use all the settings and runs fine. It also goes into reduced power if you let it cool off for a couple hours . Yesterday it went into limp mode and threw a p0108 . Just wondering if anybody had the same problem?
