[QUOTE="Strictly Diesel, post: 623800, member: 1411"] IMO, any sound that is like "grinding" at shutdown is NOT normal. I can hear mine spin down, but it's more of the "air" noise than anything. Hard to say, I'm not one that pays attention to "normal driving" temps. I do have a hill I like to test on and I put my foot to the floor from 75mph to something over 100mph on it last night. Might have been a few psi higher boost than the stock wheel, but temps seemed about the same. With my injectors and tuning, the temps (unloaded) generally flatline around 1200-1250°F. That said, in my "before" testing I did do a WOT pull with the trailer on that same hill. I was only able to make it to 85mph (from 72mph) because of traffic, but I will replicate that pull in the "after" testing so I can compare the logs and see what the "loaded" difference is. [/QUOTE]
