Hi, I have a 1999 GT with the mongoose Vortech kit. Since then I added just a mph powerpipe and changed my setting on the x-cal from 6% lean a/f (worked best on dyno run) to 2% rich. It was running fine for about 4 months. Then it started to bog down really bad (maybe lug is the word?) not violently though. It happened when i was past about 30% throttle under load, not when I just reved the engine with the clutch in. I changed the spark plugs, the problem was nearly solved. Now it only had power-losing-lugging past about 4.5k in 3'rd and 4th gear, (maybe 2nd too, the wheels spin though so i don't know.) I then changed my x-cal to 6% rich, nothing changed. I changed the fuel filter, nothing changed. I changed my COP boots about 6 months ago, so I don't think they're dead yet.
I've been trying to solve this on my own, but I can't stomach paying someone to work on my car to get this solved. Does anyone have any ideas I could try or anything like that?
Thanks guys
