So I intend to accelerate & take off driving normal. But the throttle don't pass 2.5k RPM unless i floor the pedal & RPM jumps to 5k RPM.

I recently changed the fuel pump (walboro 255), also GOD (k-tuned), & map sensor (dealer type-s)

WHAT CAN BE MY ISSUE?...

My next step might just be changing the throttle body. Any helpful info would really be apreciated....

 

Your problem is very vague, what is the problem? It won't rev past 5k?

 

It rev to 2.5k, chokes as if it gonna turn off. So immediately I floor the pedal & throttle delays to pick up RPM.

 

Info please. I'm trying to get it running properly & enjoy it & try to make it to Honda Day at least this yer. I got 3yrs with my hatch & I never go, but I have made it to the track few times.
