Apexi AFC-II injectors

[BlacktopturboSX]

OkSo ive decided to go ahead and upgrade to a GT2871R .64 Turbo on my BlacktopSR. I have a Z32 MAF and an APEXi SAFC-II. I want to keep the SAFC-II and get 550cc injectors instead of the traditional 740cc. I am doing this because I dont really have the money to get an Enthalpy tune, and I would rather do it myself with the AFC-II, and it can only read up to 550cc. Now before I get reemed by some cocky @$$hole whos small brain can only answer "search", I have searched, through the thousands of results that came up, and all I found was bits and pieces to answer my question. My question is: ---Is anybody on the forum running this setup on their SR? Did the 550cc injectors work well with a small tune on the SAFC-II, and is there any less torque/horsepower than one would get from 740cc injectors and a tune? (other than the inital loss that would come from an unproper tune...)??????If someone could let me know it would greatly be appreciated. THANKS!!!!

A guy i know locally did 335whp with 550cc and SAFCII and GT2871R .64. Did all of his tuning with a LM1 Wideband on the street.
