adnanshah247 Posted January 12, 2009 Share Posted January 12, 2009 (edited) Fella's i have a small issue. Everytime i put my foot down in my tt, i get a judder and like petrol jerk at high revs. its so fustrating! After reading tonnes about the fuel cut its safe to say that its not that becase a fuel cut totally kills power for over 1-2 seconds. mine judders and then boosts off. i checked my digital boost controller and the issues im having are at 0.7 - 0.83 bar of boost which means im not over boosting it right?! the maximum boost recorded on my turbos were 0.83. As soon as the judder goes i get a fury of boost and the car takes off but that for like 1 second as then it redlines and i have to change gear and then same issue all over again. could it be the turbos? My patience is really being tested with my sup as its cost me so much in the last 6 months! Could it be my injectors? there not sending the right amount of fuel? how to check them, my fuel pump is about 6months old so i dont think its that.

miko_supra Posted January 13, 2009 Share Posted January 13, 2009 Put the turbos in parrallel mode so that you can rule out any issues with the sequential system. Quote Link to comment Share on other sites More sharing options...
