boj, where u get this done?
i have the same prob.. same mods but hks ssqv.
i was told best to get a aftermarket ecu like power fc or safc and it'll fix the prob.
last night a black skyline was being chased after going at high speeds and ended up hitting a 4WD and pushing it into shops... now people like this are f#%ked. Giving us skyline drivers bad names.. i bet cops are keeping a eye ons kyline now .
