So my Z has been in storage for 4 years. It was ran and slightly driven every month just to keep things flowing. Today I decided to take it out on the highway and push it a little to see how is everything. A weird thing happened: everything was good other than a slightly rough idle, nothing to worry about. When on the highway in second gear at around 5k RPM and max boost there was a very noticeable "kick" almost as if the tires were loose and caught grip, but they weren't. After than everything seemed very smooth and even my idle seemed way better. Any ideas? I got all stock parts except for exhaust.
