Scooby Posted November 1, 2006 Share Posted November 1, 2006 A few weeks ago I fitted a boost controller to my UK spec TT. Since then I have been getting a slight misfire under load but only in 4,5 or 6th gear. I thought it sounds like plugs failing and changed them but it is still there. Also when on full boost the I get the warning light flash up on the dash and loose all power for a couple of seconds. Any ideas?? Could the FCD need adjusting??

Homer Posted November 1, 2006 Share Posted November 1, 2006 Did you change the plugs to a colder set yet? When you did the NA/TT swap, you did put in the UK fuel pump? What boost are you running now? 1.25 bar for a sustained 4-5 seconds will cause fuel cut on the TRL unit. Quote Link to comment Share on other sites More sharing options...
