Tommyd16 Posted January 17, 2014 Share Posted January 17, 2014 Seen a TT on eBay. Said last week one of the turbos wasn't boosting now he says it's fixed and turbos running parallel? Is this possible? Quote 'Apologies for ending the previous auction to those who were watching it. Previous listing stated that car had boosting issues on 2nd turbo which could have been because of a boost leak or a blown 2nd turbo. However, I've taken it to a garage and this issue has now been resolved. Car has also been put into TTC mode. I.e...parallel turbo operation as compared to sequential one. Power delivery is a lot smoother and better now and both turbos are working fine!' Link to comment Share on other sites More sharing options...
walbertonio Posted January 17, 2014 Share Posted January 17, 2014 It's fairly common, have a search for the TTC mod. They've obviously just decided to bypass the problem the car has though, so bear that in mind: http://www.mkivsupra.net/vbb/showthread.php?27904-Sequential-turbo-problems Link to comment Share on other sites More sharing options...
Swampy442 Posted January 17, 2014 Share Posted January 17, 2014 Yes its perfectly possible, TTC mode = true twin conversion = parallel operation. Id be finding the sequential fault and fixing it personally, its probably just a duff VSV Link to comment Share on other sites More sharing options...

Guest Budz86 Posted January 17, 2014 Share Posted January 17, 2014 Probably the exhaust gas control valve. TTC is the easy "fix" but depends how you want the car to drive. Personally I love mine in TTC now Link to comment Share on other sites More sharing options...
