what mods were made to that ads chip? what kind of engine is it set up for besides a 350 tbi? what goodys does it have over the stock chip? cam? compression ratio? heads flow? fuel rateing? timing curves? i have a stock 89 k5 tbi chip. but my engine is heavyliy modified and looking for a new chip to match my engine specs.

haha.... its an out of the box performance street cam. it wont do what you need it to. you need a custom burned chip.
