I have just purchased a K&N Typhoon intake and Holley Airmass 4-2-1 (two-piece) ceramic header for my 1991 Civic Si. Should I be concerned about the ECU's ability to handle these upgrades? I do not want to melt the engine by having the ECU run it too lean. I hope I am just being paranoid, but better safe than sorry. By the way, I will (for now) be using the standard exhaust.

Any advice here would be most appreciated
