JB4 N63 feels Sluggish
2011 550i XDrive M-PKG 103k miles
Arm front facing Intake Arm Charge pipes VRSF Catless Downpipe JB4 Full exhaust Maybe its just me but I feel as if this car should be faster, the the only codes I have are for the unplugged MAF for the JB4 to work properly. I've tried using various maps and it feels sluggish when get up to 6800rpm. I drove my back up car a 6spd F10 535 no mods and it gets up and goes. If anyone knows of a good BMW Tuner in Orlando, hit my line. |
