[QUOTE="TMCCOY, post: 1541229, member: 24484"] I've run both on my truck with my 175/80's and towed a lot with them. With the large turbine version of the 364.5 and .91, both turbo's spool very similar from stand still. The 364 *MIGHT* be a little quicker. Once under boost, the 364.5 is much more responsive to throttle input. Daily driving, the 364.5 is better but it feels like a smaller turbo as it is. It doesn't have the mid and top end the 366 has. Towing, I think the 366 was better because it is constantly spooled and is great. No difference in EGT's I observed. In my case, I moved to a high elevation (5,000) and going to the 364.5 was helpful, but I'm also dealing with crappy nozzles on my PIS injectors and emissions now so getting more response was something I thought would be good in combination with the high altitude. Just depends where you want the benefit most. [/QUOTE]
