Default Engine losing power/ surging at 5400 RPMs

Under wide open throttle in every gear but 1st my motor will cut power then regain then cut again at 5400 RPMs plus. Anyone ever had this problem, your help would be greatly appreciated, I just put new plugs in and no improvement, thanks Troy.

Do you have an aftermarket pulley on the car? When I installed an ASP pulley on my car I had the exact same problem. I put the stock pulley back on and the problem was solved.

If you can get the car on an ATAP that would be a lot of help, if it is the pulley check for knock retard and random misfire codes on different cylinders above 5400 (what mine was doing)

*Edit* - If all of the above seem to not be the problem check your pushrods to see if they are all straight.
