is it worth it to buy a performance chip for an 86 2m6 4 speed?

No. The stock chip is very well optimized for the engine already. A new chip will only help if you've made major hardware changes like camshaft, compression ratio, or displacement. In the case of hardware mods you would need to get a custom chip burned, using a WB O2 sensor and dyno to gather the information needed to design the new chip parameters.

ADS, et. al. are making a killing selling $3 chips to people with minor, meaningless changes to timing and fuel maps that probably actually hurt performance.

Is it possible to get a "Stock GM Chip" ??.

I have a ADS Road Race SuperChip that was fitted to the car back in 1986.
Allthough she does go like a rocket my Fuel Consumption sucks.
I get 150 miles to a tank.
Therefore i would like to see how the standard chip performs.

They prefer to be call Auto Parts Recylers, or at the very least, Auto Wreckers.

Well as there are only about 50 or so Fiero's in the whole of the UK i am not likely to find one at a scrap yard.

I was hoping that someone on the forum was able to burn chips, and perhaps do a stock 85GT 4sp one for me.........

I can send you the binary if you know someone there that can burn it. You'll need a 2732 eprom (or erase the one you have and re-program it).
