So, is the main point here is keeping EGT's low??? well what is low? I have the Livernois Front mount Turbo set up with a .81AR Turbine and i run about 1,100-1,200 EG dregrees at 80mph with just the truck, no trailer or anything... At 60-65mph the EGT's drop down to 900-1,000 degrees... Livernois said those temps are low and safe.

Now, i don't usualy tow anything (at least not since putting the Turbo on almost 2 years ago) BUT, I am going to be moving from Florida to South Carolina in a couple of months and would like to pull a Uhaul moving trailer... So, I would image if I can pull a moving trailer, say 3,000-4,000lbs and my EGT's at 65-70mph where no higher then 1,200 degrees I would be ok???

Good point, i am interested in seeing what unloaded freeway temps are vs. loaded temps.

From what i have seen and heard from turbo owners is that anything over 1,300-1,400 degrees while cruising is not so good...

 

1400+ is not good on any gasoline engine, if the temps are caused by being lean. You can have HI temps and the engine be running rich. The rawl fuel lighting in the pipe can yeild some high number that will not hurt the engine. But the exhaust system and turbo might not like it very much. The main goal is to watch the EGTs and boost gauge, if boosting and EGT is climbing you would not want to hold that very long, so lift off the gas.
Think of your truck as a V6 on the power area and you should be fine. Just watch the gauges closely, stay out of boost, and take your time. .

 

my AFR's are 11:1 so i should be good there... I figure for saftey sake I could pop out my 7.5lbs spring and put the old 5lbs one back in the wastegate so that it could not boost as hard too, that should keep the temps down...

 

11:1 should be fine, but your foot is going to be the best boost controller out there.
