Hey first of all I want to say thanks for the great product. I have a couple of questions. I have an 05 ram 1500 sc 2wd hemi. When I first programed my truck to the 91octane setting I noticed a big difference. When I programmed it I raised the rev limiter and the shift points a little because I didn't want hurt my engine because I didn't know what it can handle. Is it safe at all letting my engine shift at 5900 rpm? In a pevious post I noticed that you said the valvetrain is safe till around 7000rpm. What I was wondering what aboiut the bottom end of the engine? I have read about people blowing the toner ring and blowing up there engine. I know what we set the vehicle to is are own doing but I don't want to hurt the engine.Has anyone had any problems with there lower end? Also another question I had does the vehicle relearn the stock settings? I put my truck back to stock because it had to go to the dealer for an exhuast rattle and after I put it back to stock it didn't feel much different then when I had it before. Maybe I'm just going crazy who knows? Thanks again Chris

6200 rpm is the maximum for a stock truck.
At 6700 I noticed valve float.
