[Angel of Death]

Please excuse my ignorance but I don't know what a fingerstick is. I searched for it here and found many many off-handed references to it but nothing that really explains it. Does it plug into the OBDII port? I guess somehow it blocks certain codes?

My truck is a non-FE9 (at least it wasn't listed on the glove box sticker) and I plan on installing a turbo back 4inch from banks next weekend, straight tube from turbo to tip no muffler no cat. I assume it will throw codes, but they won't necessarily turn on my SES?

Thanks for your patience. Erik
