About eight months ago i droped a cav turbo into my astra and from then on its been hell ! and hasnt run propally, i have posted many threads on mig, so many good ideas and opinions but still had no luck ? (thanks for the help tho its been the only thing keeping me going). 4 and a half grand later two differnt grages and many many hours tinkering its fixed !.the most anoying thing it was just a kink in the pipe from the tank to the fuel pump ! alowing enough through to run the car but not when floored it !!!!! so dont all ways trust the pro's, (SAS perfofmance) check and recheck the simple things first.
