I looking for your thoughts

I have a 97 crew cab long bed 7.3. I have put an intake, straight 4" exhaust, 6 position ts chip and basicly the rest is stock. Whenfirst get in and drive the truck it is ***** to the wall, I love it. After driving for an hour or so, when the truck is nice and warm, it seems like it is starving for fuel. An example, I was pulling my horse trailer home from a ride this past weekend. I was heading up a hill at about 65 mph went to give it more pedal to get up the hill and there was no response. I had it floored and it didn't do anything. I had one gu ask when was the last time I changed my fuel filter, last summer. I don't put but maybe 5,000 miles on it in a year. Could it really be the fuel filter is just dirty or is there something else I can check? Thanks

Sean

Fuel filter is a good place to start. Check your fuel pressure too......hot of course since that's when you experience your problem..
Is you EBVP* still connected? It may be activating w/o your knowledge. This would certainly reduce engine power if even partially closed.
*Exhaust Back Pressure Valve

The EBPV is still connected. I am going to change the fuel filter and clean the little screen. Is it easy to disconnect the EBPV.

Clogged CAT under heavy load can cause those symptoms. Had the same issue a few years ago and when my CAT got lost it has not returned.

Sean, take a look under the intake side of the turbo, there will be a connection there with a 2 wires. Disconnect that to disable the EBPV

Thanks for your help. I will try disconnecting the EBPV and see what happens.

I removed my CAT sometime ago, but that is good information to know.

Thanks again, Sean
