i have a stock b18a with drag kit on it.. herez the list:\
Vortech Fmu, inline fuel pump, check valves, mainfold and all that and has been timed. Wastegate is set at 7-8 psi and has just a dump tube.

When i nail it sometimes it hesitates(not lagging) then goes, but it pulls ok til around 4500 and flattens out like its not getting something. It, form its in should run damn good, and doesnt feel like it should at all.... could i need more fuel even with pump and fmu.. should i use the 450 dsm injectors or will that flood my motor, or actually help?? need opinions.....

 

where did u hook up your check valve at and how did u hook it up

 

well the map sensor is on the firewall on the right said of the car and goes to a metal line then towards the TB . i placed a vaccum hose from map senosr to the throttle body with 4 check valves teed off the line. there are a couple lines from map sensor but im sure that is the one since check engine light doesnt come on
