my 2001 jetta 1.8T still has the stock ko3 sports turbo, kinda small so it starts pulling at low 2000rpm, chip, exhaust, turbo h valve gets me spiking 20-21 psi and holds 12-13psi at 7k red line.
a big jump from stock 7-8psi(150hp) to over 200hp and 255 torque.
good luck on your project and pasakay pag uwi ko dyan next year.
