Well i was in Kragen today getting a K&N, and while waiting for the dumbass at the counter i was looking at their display for the AutoXray OBD computers and stuff. Also on the display was a computer thing made by HyperTech that was for reprogramming the stock computers. This product is actually for domestic cars and trucks only, but i was wondering if anyone has ever checked this thing out. Supposedly you can adjust the Rev limiter, Speed governor, change shift points in an auto trans and a few other things. It also allows you to reset things back to the original factory settings. If this thing is any good then i might just buy it to use on my GF's auto Camaro and see how it works. It is pricey, about $350 but i guess i could use it and then return it.
