i do not have a fuel gauge so i want to know whether it is best to increase or decrease the fuel pressure with an aem fpr on a stock ecu.. i do have an air/fuel gauge. is it best to run really rich when vtec hits or semi rich...

 

Better to leave it ALONE till you get it on a dyno. Just make sure it is 48-52 with the vacuum hose off.

 

i do not hve a gauge and a friend already leaned it out a lil because of the kenji p28.. now i put the stock ecu back in and im trying to adjust it back. i guess i will hold off until i go to the dyno this week.
