eCtune

Fully build sleeved GSR. Car was previously tune with a AEM EMS. Normal driving was painfull. It made 345whp @ 15psi. Unplug the boost solenoid and retune it with eCtune It made 375whp @ 13psi 417whp @ 19psi It now drives a lot better Engine is 5years old

setup?

From memory Sleeved 81mm B18C JE piston Eagle rods Ported TK Race Head and intake manifold Ferea valvestrain Ram horn style manifold 60-1 turbo (5 years old guys), it would definitely makes more power with a gt35rrrr 3\" exhaust

And btw, I checked the ems maps afterward and I had 1deg less in my timing maps, yet still makes a lot more power. Maybe final ign is different....
