guys can anyone tell me the actual price of the performance pack upgrade for n54 135?
ive phoned 3 different dealers now, they either say "eish" and tell me they will have to phone me back or give me different pricing but it doesnt sound like they know what they talking about at all.. the first guy asked me what the pack includes? wtf, is it them that works for bmw or me?
with all the talk going around about bmw checking ecu's and so on i want to do this to my car before adding jb4 so that they cant tune me kak about boost pressures and whatever.. i was told that its a local tuners software that they add anyways so if they try anything stupid will just tell them 'it wasnt me' :=):
i know babyboss has the performance upgrade, if you dont mind me asking how much did you pay and which dealer did it for you? cooling gains worth it?
