I have a 98 gst
here is the mods
tubular manifold,20g turbo,boost controller,afc neo,3 inch down pipe,880 injectors,front mount,

the problem is i bought the car like this and it wont pull it self i thinik it is because it is getting to much fuel.
I try with the neo and i can't get it to make a difference at all
changed plugs and wires and that still didn't help.
I am trying to downsize injectors and hope that help and fixeses it i have owned the car for 2 weeks now and can't drive it and on the neo it shows that i am 100% throttle when i barley have my foot on gas am i up a creek or can i fix easy most my money went into buying car and i don't have the money for a dsm link
any help would be awsome.

Ill trade you injectors lol.. I hear it is hard to tune injectors that big on the neo or any piggyback becuase you cant adjust deadtime ect... Your messing with a airflow signal to trick the ecu.. I would check the wiring and make sure all the wires are hooked up right.. APEXI's website will have the instructions and if you need the wiring diagram for a 1g VFAQ Site - Visual Frequently Answered Questions My 680s i have are right at the top of the tuneability for the piggybacks..

I would highly recommend stopping what you're doing and shut the car off. If you try and fumble your way through it you WILL blow you engine. There are no if, ands, or buts about it. I'll find some info to help guide you but stop until I do.

Okay I found it. Read through this about 20 times and then do some more searching. It's also nice to find someone near you that is familiar with tuning the S-AFC. Definitive Piggyback Tuning Guide

And please remember, these cars won't blow as fast as my rotary, but they will blow pretty easily.

Shouldn't mean you're toast yet, but hard to tell. Once you go through the tuning process then let us know what you have.
