I have just recently purchased my 04 cobra days ago and am ready to start the mods. The best bang for the buck would be to re-flash or burn a new computer for the car but that would void the warrenty and that is out of the question. I am already scheduled for a cat back exhaust on friday as that is "reasonibly" inexpensive. I own a 1991 5.0 lx as well. With that car i went with mostly suspension upgrades (all maximum motorsports) and a couple of other small mods k&n, exhaust, shortthrow shifter etc..........Some parts from maximum motorsports would be great and are planned in the future but for now (as if 390 isent enough) I am looking for more power. I was thinking about going with a k&n filter system and or supercharger pulleys. I am very glad to finally be welcome in these formus now that i have an SVT, one I am quite fond of infact. Any suggestions or comments would be greatly appreicated!!!
