I have a 94 GT convertible. I was getting about 200miles to the tank with these mods. CAI, O/R H-pipe, Catback exhaust, 3.73 gears. I added a set of BBK Equal length headers and now I get about 140-150 miles to the tank. I'm filling up at the beginning and end of every weekend. With gas prices, this sucks. Is this normal? What are other people averaging? I do not have a fuel pressure regulater, but I do have a gauge. And it's hanging around 33. Any suggestions, or thoughts would be appreciated.

Thanks

check your O2 sensors. since you switched out headers, something MIGHT have happened to them in the process and lord knows they can be a b i t c h on gas consumption.

I can get 230 maybe even 240 if I let the needel get down there. I have brand new 02 sensor, Fuel filter, plugs, and fairly new cap and rotor. 230ish miles out of a tank isent to bad considering its blown.
