I have been usign HPT on 99/00 corvettes and have had great luck. I recently started working on a 98 and been giving me nothing but fing hassles. 1) I fried a PCM, when I installed the new PCM everything seems fine, starts and runs ok but when I got to download the file, the car throws up codes on the cluster and keeps stoping saying problem with high speed communication. Is it just me or are 98s funky?
