Does anybody have a superchips or a fastchips programmed chip for there 91-92 seville/eldorado or deville with the 4.9L v8? i emailed both companies about availability, and they no longer offer them, PLUS, they wantd $200 for theirs, when they had them in stock. If ANYone out there has a performance chip and would be willing to work with me, i can duplicate them cheaply for about $50 for anyone who wants one for their car, i would just need to get ahold of an actual chip so i could copy it for use with my programmer. whomever provides me with the chip, i would make them a duplicate chip for free so that they would have a backup incase they ever had computer damage. please email me at :

thanks for your time,
