e60 upgrade horsepower

Re: e60 upgrade horsepower

By fitting the power box does it increase the horse of the car? I guess if power box is like piggyback it will not help much in terms of horsepower right?

If I m looking into increase in horsepower remap is a better but more expensive solution right? Can some good heart people give me some advise?

Thank u many many!

Most of piggyback sold in the market require custom tune to your ride. Powerbox is a fix programmed piggyback that developed for N52 engine(All share one setting), it still does increase hp & torque. How much gain on each car? Very different gain on each car as it is fix setting for N52 car.

How much gain on average? I think nobody know. Anyone did a Dyno before & after for the powerbox on E60 or E90?

Why I claimed Tuner is very important. As some tuned car went on dyno, reverse back to stock ECU, dyno again, POWER increased......

Have a nice day ahead!!!
