Looking to install a steinbauer module to my GU patrol , witch has 3'' exhaust , aftermarket IC & Dawes valve also. When i spoke to westend diesel they told me to leave dawes valve in place & put the module in. If they install module is it nessesary for them to run on dyno because if not i will install myself. Thanks.
