My next expensive mod for my car is going to be a chip or tuning device. And i was wondering what it will do for my 95 GL performance wise and how much i should pay for a decent one. And if i dont get a chip i saw this thing on Trucking TV the other day that used this thing called Edge Perfomance like an extra computer and the used a GMC 2500 Diesel and it went from a 17.4 to a 15.2 just putting the edge performance kit in. Considering its a stock huge truck thats not tooo bad. But ya im a noob that this sorta thing so any input would be well appriacted and i also know that its a topic that comes up alot but I would feel better If i got it answered just for GEN 2 SLOs. Thanx
