Possible to add chip + bms powerbox for 325 (2.5l)

dtm1 · 11-18-2009, 10:54 AM

I was about to purchase a bms powerbox for my e92 325 (2.5l euro). But I've recently found in my area that skn tuning chip is available. Anyone have opinions for skn tuning? Can I install both? Thanks guys.

possible? yes. but it probably won't give you extra gains by doing both, and may actually hurt power

The PwrBx is a chip too, so it takes the OEM signals and boosts them. I dont think you can series wire chips to get gains from both, thats too much level switching and work for the chips and ECU to figure out.

Stick with one or the other, but remember the PBX does two main things

1) adds power
2) adds throttle response improvements so the car is much more responsive

3) the mix of 1 and 2 really make for an amazing driving experience
