I have been running the PPE 160 for about a year now as a daily driven tune. I even ran it in winter when temps hit around -50 C. I had no problems with it at all. Right now I am currently running the PPE 225 tune and I plan to run it as a daily driver also. I don't have gauges yet, but I tend to drive on the conservative side. There will be no towing, and the trans won't be an issue. I am just curious what kinds of EGT's you guys were seeing with the 225, and if you think it will be safe enough to run in the winter. The 160 was fairly quiet even when it was -25C and my truck wasn't plugged in. Will the 225 be louder? Any info you can give me would be great. I know it's a lame question, but who else am I gonna ask. :baby:
