I have a 2003 GT, with Vortech V2 Mongoose kit running 11psi. Been tuned with Sniper Delta Force. Here lately my ABS light has been coming on at random. And when I try & get on it, it's bumping my timing out, hendering my hp. Scanned it & got the c1805 also another one. I can't remember the number but it had to do with the abs cluster. What could be the problem here? Something to do with reflashing the pcm with my new tune? Or is it Mismatched PCM and/or ABS-TC Module?
