Need some help with my ka24de

[athens240]

I got a 93 240sx with a stock ka24de, obx header with a 3in cx racing cat back exhaust and 5 speed swap. My problem is the car pulls good thru all geas to about 3500rpm then drops off till around 5000rpm where it picks back up and pulls the hardest to 7000rpm. My question is how do I fix that dead spot btwn 3500-5000pm? All help is appreciated

Check your TPS it could be bad. Also check your coolant temp sensor. Also check FPR. Also check injectors. Those issues will cause fuel richness which effects torque and hp.
