EGTs high when warm
So ive been having this problem for the past month or so. First thought it was a boost leak, then a bad wastegate, and now I have no idea.
Truck runs fine, except for the fact it runs hotter than it did before (oil temp).
Trucks been getting bad fuel economy, used to be 18-20 MPG now its 15-16 MPG.
When cool the truck makes good exhaust backpressure and boost, but when warm, and at highway speed it acts funny.
When I lay on the pedal on the highway, the EBP and Boost will be very close to each other like 8:6. But when the trucks cold and im on side streets I can hit 15:8 in 1st gear!
I am starting to think either I have an exhaust leak or the EBP sensor is going bad.
This is very frustrating as ive put about 600$ into fixing this issue.
Info on truck is in my signature. TIA!

Let's cut him a bit of slack because he left out some information that is critical to us, but may have slipped his mind at the time he posted.

The FTE'r asking for help is fairly new to the community and clearly frustrated with the problems he is having. He also seems to be tired of spending money on "fixes" that are not working or being told what the problem is and coming to find out that was wrong.

Today when driving to class Boost was at 5 psi, EBP was at 4psi. My Autoenguity is supposed to come in today, rn all I have is a Edge monitor.
I hope it’s this stupid sensor,
so far I’ve bought a new intake tube, IC boots and clamps, wastegate, and entire EBP system.
Puts me at 550$ so far.

On my Edge I can’t read BARO, and it won’t read below 0, my autoenguity is coming in today so I’ll try it out after class.

Well I’ll look tomorrow morning before I leave, so if all are within .5 and the truck still runs hot with low boost/back pressure, I’d assume the issue lies in an exhaust leak since I have no large boost leaks at 25psi with a tester
