Hypertech Performance Chips.
I have to replace my 1989 corvette ECM. I have been thinking of buy Hypertech Thermo Master Performance Chip since I already have the ECM out of the car. I would like your opinion on Hypertech clips pros and cons, increase or decrease in WHP and Torg. I appreciate your help. Thanks.

The engineers that developed your car were pretty sharp. There aren't really any hidden performance gains to be had without hardware changes. At best you might get a "seat of the pants" improvement that isn't really faster on the stopwatch.

Years ago I tried a Jet stage 2 chip in my 91 (which I'll assume is similar to the hypercrap chip). I went to the track and made a few runs with the stock chip and a few with the Jet chip. Its been awhile, but if I recall correctly the car ran about .15 seconds quicker with the stock chip. I promptly removed the chip and sold it on ebay. If it were my car I'd stick with the stocker until your mods require you to get a custom prom burned.

I have a 1990 L98 with automatic transmission. The previous owner installed a Hypertech 120382 ThermoMaster Power Chip ($179) in the car back in 2002. He also installed a lower thermostat ($7), Hypertech coil ($99) and Walker mufflers ($250) (which, BTW, are loud and make that drone sound in the car -- getting ready to install my second layer of Dynamat in the Spring!). Car sounds cool and I would not change a thing. Nor would I have made any of the modifications if I had to shell out the money for them. That said, it does get a bit better gas mileage (mayber 1.5 MPG more) than my son's 1991 L98 auto and seems a bit faster as well (which is probably due more to the 3 1/2 inch exhaust versus the stock 2 1/2 inch exhaust on the 1991 than the chip).

Once upon a time I dyno tuned a car for a guy who had an aftermarket chip from one of the major manufacturers. Just for fun I opened it up and compared it to the stocker. The ONLY difference was that they set the fans for a lower temperature thermostat and REMOVED the rev limiter.
So, if you just really wanna spend the extra money, pay me half of what you would spend on the "performance" chip and I'll kick you in the ***** and we'll call it even.
