[:@] Hello guys or gals,
I've beeen having power issues, at around 95 mph when I floor it it used to picj up quickly, now it acts like it needs a push, it has 180,000 miles and on the factory fuel pump filter assembly, can the filter be getting stopped up and causing the lack of power at higher rpm's? Its a 2001 ram 5.9 gas engine

i would cheange the fuel filter and check the cat converter. did you say 95

 

Around 95 to 100 mph the thing acts gutless, never before, it has aluminum rt heads, M1 intake 54mm throttlebody, headers, and a plenty big cam and a pcm cam calibration program, before it would run around 140 easy and now its just gotten gutless at high rpm, something is restricting it bad, it stays parked most of the time but its time to unleash this beast, there are to many of those new mustangs out there I need to eat. Thanks for the input, and I am definately going to check out the converter, it has been on it from the purchase of the truck and i have read alot about people having trouble with them, so thanks again for the input.

 

Along with your fuel pump with filter and cats check the intake and your injectors too. with that many miles on her, she's probably getting a bit clogged up

 

I am running a K&N FIPK for air inlit--not clogged, and the intake is a M1, theres no clogs there, thanks for the input, everything helps
