my question is i am seeing around 4 psi and 600 degrees at 70 miles/h empty on highway is that normal?
i was seeing higher boost out of my old 6.5
this is a stock truck with a strait pipe and a 6637 filter

and i know already i need a better trans cooler it was reaching 190 empty in city and highway and around 70 degrees outside

Those numbers are in line with what I see ... The trans temp is too high ... better get a cooler or something else could be wrong ... I hope someone with more knowledge will chime in ...

yes the trans is a little hot but it was just rebuilt and i was in Chicago traffic
boost looks a little low to me

I have not seen higher than about 170* towing 7000lbs in 70*-80* weather and traffic, pulling hills ect ... that tranny temp is borderline bad ... I hope some others will chime in and comment ...

I can get to 170-180 empty when 80 outside, never towed so not sure on loaded temps.

is your sender in the pan or test port?

[paulgl26]

the cooler was part clogged and the sender for the gauge was in pieces when i puled it out lol
i see 150 on the highway 155 in the city today in a 65 degree weather

my tranny gauge should be here on wed, then i can put in my pyro and boost gauge. i am interested to see what is happening. especially since i have an e99 with the crappy cooler. next up is getting a 6.0 cooler.

@70mph I see about 6-8psi boost, and I run about 140-150° trans empty, I have seen 195° when pulling 15000# @ 70+mph.
