I have a built 2000 Civic Si with a Greddy turbo kit installed, which came with a blue piggyback computer. This is before the e-manage came out, so its pre-emanage, I have since taken it off and installed an V-AFC II along with 440 cc injectors. The car runs good at times and other times runs not so well which i attribute to the CEL on. I need for this car to pass emissions as it will soon be required for this year. Any suggestions for i may be forced to put back the piggyback computer, replace the 440cc with the 310 cc from the kit in order to get it to run right and pass emissions.
