wont rev passed 5500 when warm

[Smatt90IS]

car runs great for 10 minutes then it runs perfect up untill 5500ish then the power falls on its face recently replaced o2 plugs plug wires cap rotor fpr. i think its either my fuel pump or the ecu temp sensor or my dinan chip is screwed up the car pulls great on the down low and before it gets warm any suggestions would be apreciated o and i gave it a compression test which was perfect

it doesnt cut out or spudder it just quits reving up

Check a couple of things.

Air flow meter
Crank sensor

If you have your stock chip, put that back in and see if it makes a difference too.

k wheres the crank sensor and my maf is good i unplugged it while the car was running and it ran way worse

Check the operation of the WOT switch in the TPS. It sounds like yours isn't working.

okay its kind of lacking in the mid range to but if its not on the WOT on the TPS the maps probly fucked which i think it is cause it only does this bs at WOT thanks any other ideas would be greatly appreciated

cap and rotor? always check those if a m20 is running like shit.

cleaned c101 connector and put some dielectrical grease car runs perfect! took it on some curvey roads for an hour and beat the shit out of it and it did not cut out or hesitate at all times like these remind me why i love the old e30 haha
