Looking for some insight with tuning a 2018 G56. I recently swapped from EZlynk to EFI live and installed a steed speed manifold with a S476/87/.90
Shifting is terrible and RPM's rev when at lower RPMs 1700/2100 and when going all out 3000RPM's plus. I'm sure it's something that can be fixed as I didnt have these issues when shifting with compound turbo setup. Seeing if anyone has had any similar issues and what all they did to fix it..
