An extremely good deal or a Hoax ? Cheap Performance chips

[voivod]

Hey guys,
I found this and a few similiar other "performance" chips that have been listed on ebay .
It looks too good to be true , and maybe it is .
So just wondering if its real or just bull stuff !

Rip off. What things like that usually do is add a resistor in line with the MAF sensor to send the computer false readings about airflow so the computer dumps more fuel into the motor. More fuel is not always a good thing, especially if you don't have the increased airflow to go with it. Running a car rich will not gain you anything except poor fuel economy.

Save your money and buy the real deal.

Complete and total trash. Doug at "BamaChips.com" dyno tested a "performance module" purchased on eBay and found a 20HP LOSS.

One of my customers tested his jet chip against stock, and found the jet was a 12HP loss from stock!

Mac Units stand the test of time, built to withstand drastic changes of temperature, moisture and erosion.

Whew! I was worried about it eroding... wonder what kind of mud slide or silting would occur in the engine if they hadn't tested it??

By running a car’s engine leaner, vehicles have gained more miles per gallon (MPG). Proven test results have indicated that by adding more gas to the engine’s fuel/oxygen mixture, an increase of up to 25hp+ can result without giving up MPG’s (1/2 mpg).

Well, which is it? Does it run lean or rich? You can't run lean and rich at the same time.

If it looks like a duck and walks like a duck and quacks like a duck.... it's just proof that there's a sucker born every minute.

Hahah, I love it. Theyre just throwing random facts that sound good in there, regardless of what the thing actually does.

Lean=less fuel=more power=increased heat=melted piston.

it wont help out your fuel economy unless you are driving it hard all of the time- because during cruise your computer is focusing on the oxygen sensor, not the MAF. The computer keeps your AFR at ~14.7 based on the o2 sensors voltage
