Hi everyone. I bought this car a month ago. Has a vortech v1 s trim intercooled, long tube headers, off road x pipe, 4.10 gears. Those are the known main mods but it could have more as i havent done the work. All work was done previously before i bought it. Anyway the car has been running perfectly until today. I was merging onto the freeway and punched it in 3rd and redlined it. Right when i shifted into fourth it started bogging and felt like it was missing. I looked at my air/fuel gauge and it was all the way rich out of nowhere. The car burned, not leaked a quarter tank of gas in 20 miles. Tons of unburned fuel coming out the exhaust and will not idle, just dies. Car runs like complete crap. I am at a total loss as to the problem. Any ideas?

thanks
axel
