when I drove it to the shop it was running normally because there was a vacuum leak hence no boost. Thank god we didnt find out on the dyno, had to have my room mate took it from the shop coz I six bloody days and told me it cuts out at 5000. Yeah we did drive it to and back from the exhaust shop, and we didnt hit 8 psi it was only set on 4 according to the gauge for some reason the car is running rich and I thought without the bigger injector itd would be the opposite, im not quite sure. the car is sleeping outside waiting for the injectors and fuel pump to arrive before we get it tuned
