Gday Everyone,
I have just installed a Dual-Stage Turbosmart Boost Controller on my R33 GTS-T. Have connected it up as per the install diagram has said to do and when on low boost the car pulls fine and then when switching to high boost and running it, the car jults when accelerating. Low boost setting is 7psi and high is 10psi. Any ideas what this problem would most likely be?
Thx James
