NUTLESS SHO

[Brook24v]

Hey guys, I need some help. My atx has not near the power it used to have. It has 150k with no 60k and I have tried to cure the problem by replacing the fuel pump, fuel filter, motorcraft plugs and newer wires, newer maf, cleaned air filter, and it still sucks power wise. Do ya think I just need to spit out the money for a 60k or do ya think its something else like bad cats or a flat out tired motor? Oh for some reason if I pull up somewhere then put it in reverse to back up the rpms will raise a little then drop and die so something isn't right. Please help, I have over $8,000 bucks into my SHO and it doesn't even run that good. take care guys

Need More Information...
Have you pulled the codes?
What is the maintinance history?
Where does the power drop off?

Agree, is this analysis from the "butt dyno" or are there any numbers to support the loss of power? Compression check?
