I just got done looking at ebay auctions...there is a "performance chip module" that supposely increases horsepower by 20. If anybody could reply with some useful information on this item it'd be greatly appreciated.

 

yeah and it will prob make ur motor go boom na most of those chips on ebay are rip offs anyway dont waste ur hard earned money man

 

those are not chips. those are resistors that trick your computers iat into thinking the air coming in is colder than it actually is.

start messing with those things on a supercharged car and your engine may go boom

 

Thats all a Cobalt SS needs is more fuel.

 

Warmer actually, not colder. This will cause the computer to lean up the mixture slightly. Helps with power as all factory PCMs are programed to be slightly rich for safety sake.

Generally not the greatest idea to cripple the computers view of the engine, especially one so important as the intake air temp.

 

actually it's colder. it advances the timing, and dumps more fuel into the engine

 

Either way, eBay chip mods are usually a bad idea.
