Alright guys, I just did a customers truck. We ended up at 426 and 801 on my mustang dyno. Trans is in the process of rebuild. His goal is 550 to 600 hp. I've not pushed one quite that far yet. Has anyone here had the experience with hpt? I'm looking for precautions and tips you might have used. I think we have all the support items we need, and he is fully aware of the dangers. Appreciate the help
