Hi All, recently purchased a 430d after selling my 120d coupe.
Looking for a reliable and effective tuning box - any recommendations?
Quick browse online and the blue spark "pro + boost"seems great value for money;
+90nm torque (560 to 650)
+ 56PS (258 to 314)
Potential 10% increase in economy
28 day money back
2 year warranty (haven't looked into the specifics)
£279
Anyone here tried one out?
Appreciate this is not a 1 series question but the 4 series forum is poor at best!
Thanks
David
