I have a 84 GN with a new turbo that runs good most of the time.Problem is it over boosts under full throttle and pings bad.I've replaced the 2 vacuum lines to the waistegate but still the same problem.Beofre I replace all the vacuum lines can some tell me how to bypass the waistegate solinoid to make sure that is not the problem.The waistegate looks fairly new and seems to be working.Any other ideas would be appreciated.
Thanks.
Thanks.
