I'm about to take the plunge and get a 2.93 pulley and custom burned chip for my cobra but in the back of my mind I am worried about any possible engine or supercharger problem that can come with it. Were our cars built to handle this much PSI? I know my warranty will be voided and I wouldnt be able to afford large repairs such as an engine swap or anything. Call me paranoid, but I'd just like some reasurrance from you guys...the experts. Will the car be running strong still after 50,000 miles? I know there are no garantees because these are so new no one has that many miles on their car yet. But whats the most miles anyone has on their car with a chip and pulley? Has there been any problems linked or related to a chip and pulley upgrade? Thanks, I appreciate any info you all can give.
