Does anybody make an aftermarket tuner PROM for a 1995 Seville SLS (VIN Y)? I heard www.ecmprogrammer.com makes one, but they don't list the price on the web, so I'm guessing that means big $.
I got a quote back for $329. They said they could get rid of my P039 TCC/VCC code too. Has anybody heard what type of performance change this aftermarket PROM makes? Is anybody running this PROM?
