I WOULD SMACK MY FRIENDS NEW SI CIVIC AND NOW IM HEAD TO HEAD WITH HIM???? IM TUNES ON THE NEO AFC CONTROLLER AND THE THING I DID DIFFRENTLHAT BE MY WAS CHANGE MY INJECTERS TO 440 FORM STOCK, AND I HAVENT TAKEN THE CAR TO GET RETUNED WITH THE NEW INJECTORS. COULD THAT BE MY MAJOR LOSS IN HORSEPOWER? TOO MUCH FUEL?

 

go back to stock, then try the race again. ( it is possible to much fuel or cat is coming apart and clogging ) unless you have a full flow cat now.
