There usually is an immediate power increment felt after the installation of a piggyback. However, we met many who installed piggyback reported to us their car returned to stock car performance after a certain period of time. The period ranges between 2 - 6 months, and some as short as 2 weeks! This could be possible because the modern ECU are intelligently designed to go against and adapt to the faulty signals it receive from the Piggyback module.

I have experience with 2 of BMS's piggy back units. 1st was the Power Box for my na I6 325i. Installed in Nov 2009, it never missed a day's work, improving the performance of the 325i. Sold the car i Oct 2012 with the Pbx intact and working a charm.
N20 JB1 installed in my F30 328i since Feb 25. When first installed, I felt an improvement but more so over the past few weeks, improving performance over this time.
What about those who have their JB1 installed for months? No complaints from them.
What about the E90 N54 and N55 army? Going strong I read.
So, who is this 'tuner' you made mention of?
