STAGE2 CHIP 350,5.7L Corvette Mass Air Flow MAF TPI L98

This chip is for the 1986-89 TPI  cars. It is a chip programmed with a hotter fuel and timing curve to pull as much hp from a stock to nearly stock car and thus REQUIRES at least 91 octane fuel and a 160 degree thermostat.  Fan temps will be altered to come on earlier to help keep that motor cool so we can achieve as much gain as possible. I will need the model, year, engine size(and whether the car originally came with that size engine), transmission info, injectors size if altered from stock and pretty much any modification info for your car so I can make sure you get a compatible chip that will work for you since different computers and memcals were used in the various years. This chip won't be altered for larger than  26lb injectors which can support up to a 400hp motor.  I will alter to run with a mild cam and head upgrade as well as up to a set of 26lb injectors. If you have any questions please email me

My chips usually get either the same gas mileage or a slight improvement with at least 25hp increase. But the increase is directly influenced by the modifications made to the car.  More mods and that hp number can grow substantially.

NO HASSLE REFUND: If the chip does not perform the way I claim in your vehicle, I will either offer to make you a new chip or refund your money in full including shipping charges.

Any questions or if you wish to use a credit card to pay for your auction while avoiding  your credit card info being passed on the internet. Give me a call 336-471-2827.  I do not put credit card info on any computer system for security reasons.

This is a picture of what you will receive. I switched to using the adapters instead of the complete memcal due to the excessive cost of the memcal and the problems I had reprogramming GM's cheap chips.

To use chip you plug the original memcal into the adapter with the brown chips on the same end. NOTE: You won't be receiving a MEMCAL as pictured from here down. You will receive the adapter and engine management prom pictured above. Below is just for installation reference.

Then just put this whole assembly back in your computer and off you go. You can return to stock at anytime by removing your memcal from the adapter and placing it back in the computer by itself.
