Also something to note around Mighty Car Mods: we are normal guys and are not trained mechanics. We like to make interesting car mods and show you how we’ve gone about it, but we can’t promise that anything we show you will work for your particular car, or that you won’t harm yourself, someone else, your car or your warranty doing it. Please be safe, be responsible and unless you know what you’re doing, do not fool around with very serious machinery just because you’ve seen us make it look so easy. Talk to a qualified mechanic if you are in any doubt.

I bought a golf ball detector from the same Ebayer, no good either. Hope you reported him too.

BaconNBeer says:

I was hoping it would blow up. At least it would have been fun to watch it go up in flames.

Radical scam!

Alan Bray says:

Many of them you have to drive 150 miles KM or so so it can re map the ecu to your driving habits

CHEVY BOY!!!! says:

I can’t believe it, I put 1 on and I was flying. Mine said 100hp extra!!! I put it on and I was smoking the tires everywhere. I went from a 4cyl to a v8 454 with a blower!!! I been hauling ass so much that my hair is now slick back permanently. I’ve already gone through 3 sets of tires this month. Well I’m about 12-15 speeding tickets now this week and so it’s time to retire my car. No 1 should have that much power in a 89 chevy cavalier.

That’s my store and I’m sticking with it.

Igor Zdanowski says:

It’s like a placebo

aly nicholls says:

removing the info on the chips is common practice its done to stop people copying the circuit, its also done by less reputable engineers to hide the fact that the circuit is junk.
you would be amazed just how many devices have the important ic chips de-tagged.

My friend used an ebay chip on his 1995 Mercedes E420 and it removed his governor. His top speed was 130 before the engine cut power and after the chip he was able to hit 137 before running out of road.

Moog gets a haircut…..on the next Mighty Car Mods….see us on the Faceballs at balls/balls/balls.com ROTFLMAO!!!!

Stanimir Rankovski says:

There are some “chips” that do give you power but its no more than 5-7hp. And ofc they are not 20 bucks.
P.S. Also it works different on different engines.

Ferrin DK says:

you just need to put alot of sticker on it…. that’s where extra HP comes from

2.5M subs=confirms=the more/stupid/worthless/mindless the channel, the more subs. super super stupid 7M and more

How to turn 3 minutes of instructions into 30 minutes of mind-numbing blather.

Ferrin DK says:

and you bought the wrong switch i guess… i got a performance chip off of ebay for $20 and it gave me over 9000 HP

Mark Nembhard says:

Good video but I think it could of been shorter in its explanation

stumpy0227 says:

Most people don’t have a dyno to prove or disprove HP gains/losses, people that buy those, are just going on the THOUGHT that it’s working. The leds make you think it’s working, when it ain’t.

BaconNBeer says:

I think you are susposed to run it for over 100 miles to get the most from it. Who knows.

harry boothole says:

i could do a better wiring job than that if i was drunk

Brian Poat says:

Scrap parts gathered for free and sold for $20 to those joes that know nothing about cars and so the guy made $20 for nothing. Now multiple that by say 100 or more.
