I am adding a 255lph fuel pump to my 05 STi in preparation for larger injectors and turbo in the future. Will I see any real changes, or need to make any corrections due to JUST the fuel pump? I already planned to log it and try to see if anything changed, but I may not log the proper parameters without some guidance.
Current mods are:
-Perrin FMIC
-K&N Typhoon
-Cobb light pulley
-IXIZ A/O Sep
-Port/Polish/Ceramic stock elbows
-APS 3.5" turbo back
Thanks for any assistance, and I did read the tuning guide (quite a few times) and tried to search for my question to no avail.
