Ive ended my free period that lasted about a year.
A tune would help. Unlocking just your torque management alone, will help your car feel much stronger.
In the years below 2000, the PCMs have less setting to enhance, but the main tables are there.
If you were to go BIG HP, Id say change out your PCM to a newer version.
If you have an automatic, you'd like just my tranny tune at a reduced price than a full tune.
I would highly suggest you see Phil, He will do an excellent job on your Vette and make you smile everytime you step on that gas.
