That just seems a little late to lock in at 205 on the freeway I never get that high but in stop and go it would definitely help a ton

Have you checked to make sure your cooling stack is clean? You might be surprised how much junk can collect in a radiator over years of driving.

wonder if I could just get a different temp spring,,bet thats all kennedy did.humm

I did a comparison of the 2, and I can tell you it's more than just a spring change. I compared 2 stock replacement hayden's and his, and the 2 stock styles were the same, but there were some subtle differences in the clocking of the shaft of his, how far it rotated, where it sat in the cold position, and the springs were obviously different.

Your stats aren't even full open at 205. I posted up screen shots before from the manual, but rear starts at 180, front at 185, bypass closes at 212, but both stats aren't full open until 230 degrees. So at 205 you're only getting maybe half flow through your radiator.

The low temp mishimoto stats are fully open at 190

I'm about to put mishimoto high temps 185/191 in mine, seams fan clutch doesn't want to engage till 190 and I'm pulling ect to 180-185. I was tripping ac hp switch In houston Tuesday sitting at idle...
normally run down the road at 190-195 when it's 80°+ out.

So I bump the TStats 5-10° which cases fan clutch to engage quicker.. and forces more air across the cooling stack especially at low speeds

Be nice to see what happens with that solid fan hub

What you and I do is totally different. I literally never tow. With the high temp stats in I rocketed straight to 190 and then climbed from there. It's wasn't coolant temp that worried me though. It was the oil and trans temps that kept climbing. With the low temp stats all my fluids were much cooler overall.
