BMS stage 1 / JB4 Tune

NY535i · 08-25-2017, 09:42 AM

Hi guys I'm ready to pull the trigger on buying a BMS stage 1 tune for my n55, to give it a little boost in power. My car is out of warranty and I'm kinda of skeptical / weary of the tune to see if it would cause any issues or dash lights if installed or after running it for a while

If anyone could shed some light on this or share some positive / negative experiences it would be greatly appreciated.

My experience: this is my 2nd Stage1.
-1st was on my 11 N55 X5 and noticed it stressed the OEM injectors which were changed a couple of times by BMW.
2- my current 14 N55 535 which has been smooth but I don't drive this thing hard UNLIKE the x5. I beat the x5 everyday traveling approx 70miles a day for work..
SO, you'll prob just come across Injector or coil Issues which will make the car feel jumpy alittle. Which is very common issues with bmw's anyway.
