KA24DE 4000 rpm flat spot

[Fibre guy]

It's a '95 bone stock s14 and whenever you get around 4k rpm it feels like it won't push any more (Like it hit redline). I had KA24DE in my s13 and it felt 3x as strong and went all the way to redline. I'm fully aware of all the differences between the two before the smart @ss posts start rolling in.Also if you push till 5000 rpm it kicks back on enough to make the back wheels hop in 2nd gear. Got a check engine light but haven't been able to read it with consult due to laptop power issues.I'm getting ready to rebuild the motor anyway as soon as I deem my RB 100% reliable.Just posting to see if anyone else had this issue.

I would also like to add that it was hopping with some really grippy ES-100 Yokohama rubbers 90% tread. Wife loves her car...
