Is it a boost/vacuum leak or water leak? If vacuum you can bring it to a welding shop and have them fix it. If it's water, depending on how big the leak is, you can add some GM tabs to the system. They work pretty well. Make sure your intercooler pump is working as well.
Contact proptop if you have additional questions on the Syclone. He knows them very well.
Good Luck.
