a98pmalcolm Posted October 13, 2012 Share Posted October 13, 2012 (edited) Hay all. As some of you know I'm now running a single turbo set up. After mapping yesterday the car felt amazingly fast when the mapper took me out. And on the drive home, it ran a treat. But I'm getting the most annoying problem as from last night. I'm getting ridiculous boost spike in low to mid range. Whether its on the 1.6 bar map or 1.3 bar map the boost shoots up to about 1.9 bar and just coughs and runs pants. In 5th and 6th it all seems to be fine. I'm running 7psi strings in both wastegates. So that shouldn't be and issue. But its strange how straight after the mapping the car felt great. So it leaves me thinking its a technical issue maybe. I'm about to go check that the wastegate vacuum pipes are ok. Anything else you lot think that might be with checking?

a98pmalcolm Posted October 13, 2012 Author Share Posted October 13, 2012 I'm not sure on the AFR rating in all honesty I bought the turbo 2nd hand (new) but from someone rather than a company Quote Link to comment Share on other sites More sharing options...

Ryan.G Posted October 13, 2012 Share Posted October 13, 2012 Paul, check all the wastegate pipes, if another has split like on dyno then this will be the problem Quote Link to comment Share on other sites More sharing options...
a98pmalcolm Posted October 13, 2012 Author Share Posted October 13, 2012 Ok thanks ryan and johnny. Will check for splits Quote Link to comment Share on other sites More sharing options...
a98pmalcolm Posted October 18, 2012 Author Share Posted October 18, 2012 Solved. As Ryan said it was a vacuum pipe. One that was to close to the maifold had melted. So replaced them all and tidyed them up. :-) Quote Link to comment Share on other sites More sharing options...
