hey guys today i notised at cruising speed my egt is reaching over1500 im running a smarty sr on 9 pod 55. any ideas? outside temps in the 60s today yesterday no problems outside temps in the 40s

 

so u r saying, just cruising at light throttle u have those egts? wow, either your guage has gone kaput or1 or more sticking injectors? do u have a heatgun? its another way to see were your temps r at. granted its at idle, but if u have stuck open injectors i would think it would show for sure. good luck in finding out whats up.

 

btw, if u fill out your sig, we can help u more. what year is your truck? is it an early 05? if so your intercooler is plastic and could of cracked. were is your boost at? im just spitballing a little. in retrospect, i dont think u have stuvk injectors cuz to reach those high egts, just cruising, u would think the truck would be accelerating on its own? IDK. curious

 

gauge and prob are less then a month old temps come right down when i let out of peddle. yes cruising no load. runs smooth at idle

 

2005 6 speed boost 10 pounds at cruise four inch straight pipe exh

 

fuel press is low to cp3 only about 6psi at cruise but only saw egt high today

 

Sounds like you have a boost leak and the early 05' trucks have the plastic endtank CAC's. That or your turbo is caput.

 

dought boost leak will make 26psi if i put my foot in the pedle. this is at cruise speed min peddle in put

 

it could be the gauge but looking in to other poss also will be checking things tomorrow

 

Try running 3 or 5 at 99% just to note egts. Not real sure why you would run 9 at 55.

 

it allows me to dial it up at will and much more drivable around town turned down. egts were good till yesterday have been driving around at 9 and 55 for weeks now and no trouble.

 

I agree with Rye... take it down to 3 or even stock and try it.

10 psi boost at cruising seems very high as well. 4 is closer to norm.

6 psi fuel pressure before cp3 from a stock pump at cruise is fine as well. As long as you have positive pressure, that is enough.

 

set it back to stock still grtting between 6 and 10 psi cruising an 65mph but egt seems better.

 

what egt temp do you run at 65 mph?

 

ok now its doing it on stock setting. thinking bad pyro
