My friend has a TVS stock pulley and the IAT2s climb much faster than my m62 wth a 2.7in pulley.
We both have identical cooling mods: Option B, DualPass, ZZP H/E.
During a 2-3 pull my IAT2s usually go from 105-125. His will go from 105-130, and then heat up to 135 after letting off gas.

I did the install for the dual-pass and option B on both cars, both are bleeding correctly.

His TVS setup makes about 20-21psi and my m62 2.7 setup makes 15-16psi. My exhaust flows better.

 

If u think they are bled correctly... check is intercooler pump.

My money is on a bad pump or trapped air.

Give the pump a tap with a rubber mallet and feel the lines for moving coolant.

 

135 is bad after a 20psi pull? In what world?

 

Very true.. .good catch. I forgot this is a TVS vs a M62.

Although the TVS is more efficient, it's moving more air than that 2.7 M62.

 

thats nothing ive had 170 with similar cooling mods and pulley
sounds like the motor is stock with minimal exhaust

 

LOL, 135* is IAT2 at idle in Arizona!

 

Exactly, when I see IAT2 below 140 i'm super happy, i'm not even talking about WOT pulls. I only get worried when I see 170+, that usually means the pump is out and it will go over 200 on a pull if so.

 

That's what I was thinking, just read so many posts about people saying the TVS is "way cooler", my car is also a ion redline, it's possible that could make a difference on airflow over the stock HE since there's more room in front of it.

His TVS is on 93, and timing hates high IAT2s on his car.
