<p>[QUOTE=&quot;mhyn, post: 8722757, member: 24122&quot;]it&#039;s ok to change parameters when truck is under warranty. You can&#039;t change something that will damage engine if you use standard or pro versions. The DL must be legal. When you use legal software they see who and when parameter changes were done. If DL is a cracked it will let 000000 in tool ID place. This will freak out Detroit. I have heard there is one more version of DL. The Engineering version. No independent user or shop has legal engineering version of DL.&nbsp; With this version you can play with many sensitive settings that can effect emission,..[/QUOTE]</p><p><br /></p>
