S4 B5 2.7 blah blah blah. Need speed, need power and I want it NOW. I think my left turbo may be giving up as there seems to be some oil being passed to the cooler (more than normal) so I think it's car off the road and upgrade time. K04's Milltek exhaust with sport cat uprated fuel pump injectors (idea's please) FMIC large oil cooler MRC remap. Have I forgot anything before I see how much this is going to kill my bank balance or would it be better buying 1 K03 to replace the suspect 1, selling it and buying a RS4 as the way it looks I will be spending 5k alone on upgrade parts.
