I finaly finished the instal on my 2 belt novi 1000, my combo consists of the 1k,upr powerpipe, ebrock preformer heads, rpm intake, crane cam, acufab 65mmtb,ect... aswell as 38lb injectors with a pro-m 80 calibrated to these injectors, my problem is that at idle its running so rich its backfiring, it fouled the plugs badly, i dialed the fuel presure back to 35psi with the vacume disconected and it was the same result, is it pissoble that the maf is faulty? would it make a diffrence that my maf is mounted upside down? there are no vacume leaks ect but the car is drowning at idle.

any help would be apreciated
