Hello, i have a 1990 Nissan 240sx with 76mm turbo 5.3 swap. the car ran and idled fine, i switched out my walbro 255 for a 400 lph fuel pump, and the stock injectors for Simens deka 60lb injectors, i started the car up and it idles very poorley, when given throttle it doesnt rev up! is this happening just because the pcm needs to be remapped for the injectors, or something else? Thanks!

yes you need to have the pcm tuned

yes, i will be having it tuned, i just want to make sure that this is common, because the car will barely even idle, i would hate to get it to the tuner and have them tell me something else is wrong

yes its common.. and dont start the car up anymore until you fire it up at the tuners... or put the stock injectors back in and then take it to the tuners and then swap them over and have it tuned then.

If you keep running it with the wrong injectors...something could be wrong by the time you get to the tuners.
