98 vs 99 LS1's
Does anyone know what the difference is between the 98 and 99 LS1's?
Is it just the ECM or what?
I want to switch From a Hypertech programer to a SCT,but they don't make one for a 98 or a 97 vette. The Hypertech programer is a joke!!!
Can I just change the ECM or is there more to it?
