Jessie, it is curious that with your mods you would run rich while most folks have a lean issue. If you do not have obdii capability tied into your Zietronix setup, I would suggest buying an inexpensive scanner to check a few basic parameters. Using obdii instead of dedicated sensors will show you what the ecu is seeing. Looking at your ltfts would tell you if you have a faulty injector. Also a very low/high ect signal
