Needing some help!
I'm looking at Bluefin for my 140 tdi but im just not too sure!
I've nearly got the funds and i like the fact that i can remove the tunning for trips to the dealers... ... so what is the verdict from other 140tdi bluefin users?
Any mpg gains/loses??
And i would hope at 600 quid there would be noticable torque/bhp?
Thanks in advance
