Modest HP gain
Have a 95 LT1 AUTO with the 3.07 rear gear. The car has 52k on the clock and is only used for cruising and an occasional trip of a few hundred miles. Bone stock but with Borla exhaust.
I asked my mechanic what can be done to get the best performance without the expense of heads, cam, or intake. It's a Ca car so headers are a problem here.
His advice was to change the thermostats to a lower temp and set the fan speed to also come on at slower temp. I think he said a 160 degree thermostat. His reasoning was the Motor starts to lose power up around 208 degrees and the lower operating temp would prevent that.
His second suggestion was to install a performance chip and do some reprogramming to get the most hp and torque. About 30 hp should be the expected gain.
Since I' new to changing anything on the Vette to enhance the performance does this seem reasonable or am I wasting my money? Thanks in advance for your feedback!

You could reprogram the computer, but your not going to get anything near a 30 hp gain out of a stock car.

If you want more acceleration you could try a stall converter.Make sure to add a tranny cooler as well.
Turning the fans on sooner is a good idea.
You could cut the lid on the stock airbox and run a K&N filter or the like.
A dyno tune will give some hp with the airbox mod and the exhaust but would have to be done again if you mod more later.
1.6 roller rockers is worth a few ponies.
An electric water pump and/or under drive crank pulley is a few ponies as well.
A good solid tuneup and fuel filter for starters if it hasn't been done.
Not much to be had without spending $$$ so leaving it alone and enjoying what it is is a viable option also.
If you are willing to bite the bullet a set of nice 180cc AFR cnc cylinder heads would give you power everywhere and drive like stock when cruising.

Gears first.
Delete the Throttle body coolant.
The Fans can be programmed in the contents table. Changing the MPH, oil temp also the fan/s speed percentage.
1.6 rockers will add apprx .30 lift, a slight increase of power.
A tune after these simple mods. I believe 30 + extra.
