Won't rev past 5-5.5k please help

[evo8yea]

Ok so I went to take the car to the dyno to get tuned and the car will not rev above about 5k.

This is what I've checked and replaced so far tying to correct the current problem.

Coil pack

ignitor

plugs and wires

Cam angle sensor

Maf

coolant temp sensor

checked over all the IC pipes and hoses and makes sure they were tight and clamped good which they were. And still having the same problem. I am using Eculink and I also turned off the Antilag and still not reving above 5k.


I'm at a complete and total loss of what to do next. Any help would be amazing!


Thank you

Ethan

Check your CAS/CPS and your O2

you could have a clogged catalytic converter, if it runs too rich, it could easily melt and clog it up, try unbolting it and driving it, it will be very loud but would tell you if it is clogging the exhaust
