hello all.

i dont really have much experience with turbo cars as this is my first turbo car

right first of i have a 04 Vauxhall Astra coupe turbo, which i bought with a dump valve and boost gauge fitted by the previous owner. He seems to have blocked the old dump valve off instead of using a one way valve. i,e using a thick metal washer.. i believe its a standard turbo and not a VXR

When i put my foot right down the gauge only reads 0.5+ bar and fluctuates a bit at that pressure.

Does 0.5 bar seem a little low to anyone??

thanks for your help guys
