JS’s ’97 GST has very basic upgrades. A front mount intercooler, manual boost controller, and upgraded 16g turbo. Tuned via ECM Link (DSM Link) we manged to go from 191whp/170tq at 6psi to 240whp/237tq with tuning and 11psi. The wastegate on this set-up is very weak as you can see from the fluctuations on the dyno chart. With the addition of a stronger internal wastegate and additional tuning this set-up should be able to make around 280-300whp safely.
