When to the dyno this weekend and was disapointed. My truck made 500. 8 hp on turbo nad injecters. I was happy about that. When i tried water meth it bumped me up to 538. 00. When i put the red line box i got no additional power out. THe box seems to say that every thing is ok. Had anyone ran over this proble before. Also i tried the Mad ECM and it dropped me to 405 and 410 for hp. So i dont know why my truck didnt like it but it didnt. Hope that this had happened to someone else besides me.
