hey guys I got a 07 5.9 and already have a bully dog on my truck with the crazy larry setting and very pleased with it but I was looking for somthing that will stack with it. I was thinking of the tst powermax cr. I have herd it was a good power adder and should be the last one I need. Is this a good idea to stack it or should i just run it by itself? also what would I need to do to my truck to be able to use it safe and on the higher settings. any info will be greatly appreciated guys I dont know much about these and dont want to tear my truck up.
