i was offered a computer chip upgrade for my 1990 z24 automatic. It is made for exactly my model, but i have heard bad things about chip upgrades.... anyone have any experience with them?
Useless. Unless it comes from FastFowarfPerformance it's useless.
Most chip from REAL BIG COMPANY (IE: superchips, Hyperchip, Bilmar) only gives 1-2hp. Not worth it for 200+$.
Those ebay chip don't work at all. The real chip goes IN the computer, not on a sensor.
