My father has a cherry 86 coupe with 17,000 original miles on the clock. He has installed a Borla exhaust and a K&N filter. He is considering a new performance chip. Anyone have any experience with this?
your father has not even begun to modify his vette, so there's no need for a custom chip. if you're referring to a commercial, off the shelf chip like Hypertech, that is most definitely a waste of money.
ask your father to join this forum so we can answer his questions directly.
I wouldn't bother. It's a stock car. Make sure the car is up to spec for STOCK before you go hunting for more power.
1. check plugs, wires, cap, and rotor
2. check your _base timing_. 100% of the Corvettes I've seen got a tremendous improvement just by reestablishing the timing.
3. remove the MAF screens.
4. adjust your TPS (search here for instructions)
5. Run a little redline injector cleaner through it.
6. change your fuel filter.
Then come back and let us know if it improved the car any.
I don't agree with everyone here. A chip is a affordable way to keep the car cooler, remove troublesome emmissions dtc's, adjust for the factory rich wide open settings, put in some nice punchy timing tables..
The vettes do come tuned up pretty good from the factory but its still not a complete waste.

Over the counter HiPo chips are a waste of money. Custom tunes are

The problem with a custom tune is: It's dialed-in right up til you do something else to the car. If you're using a chip to make the fans turn on sooner, you're not gaining a whole helluva lot if there's another problem with the system (like a plugged radiator/condenser area). If it's setting emissions DTC's, aren't you better off figuring out why?
The problem with custom programming around stuff is that you're not really making the car better long-term, you're just compounding problem on top of problem. ("I chipped out the emissions stuff, neglected to fix the vacuum leak to the EGR valve, now I wonder why it won't pass emissions?")
IMHO, I wouldn't get a custom tune until you break into the longblock...or you finish your exhaust mods (read: add headers) and decide to pitch your $300+ tune when you tear into the longblock.

it might be noted that his tunes are $150, new ones on top of that to account for additional mods are just $50 more
My 86 is stock with the exception of going cat-less. Alvin's tune is making 13.8's at 100 MPH. This car new didn't do that good! I get 24-26 MPG all day long (hwy) and she runs & sounds smoother than stock. On pump gas!
