took the car to the track yesterday.. after a couple of runs, my car was bogging as i drove back to the pits.. i hit rev limiter in 4th in those runs.. running b18b w/ jrsc @ 6psi... stock pump, stock injectors

driving it home on the hwy, the car seems to bog or misfire when im keeping the speed/rpm at a constant.. as soon as i accelerate, it seems to open up and feels normal.. idle is ok (750rpm)

i havent checked the car yet.. first thing ill do is check spark plugs.. and iacv..
any other suggestions?

thanks

 

check your compression

 

replaced the plugs and wires.. seemed to help a bit.. car still hesitates in the lower rpm

 

most likely a fuel or spark problem.
