I found this on thing on ebay called a Power speed chip. Apparently its something that plugs right in, and gives you an increase of about 20 hp.. Is this thing a fake? The guy has good feedback..

This has been posted alot of times already. This thing just does not work period

 

cool thanks for the warning.. I was just searching for scion xb on ebay, so there was a lot of stuff. I saw this grounding kit by jdm on there. Is that worth it? Does it really improve performance to the electrical components?

 

it's probably a universal type kit and will probably have the same effect as any other ground kit out there... but watch those ebay ground kit shipping costs, they charge an arm and both legs...

from what i've heard ground kits provide: better sounding audio, brighter lights, and lower rpm's at idle...

check this thread out for an excellent DIY setup:

also i think groundfusion.com has a pre-cut scion specific kit...

 

that thing is a resistor or something, its not a bunch of wires like the grounding kit..

 

plugs in and the computer thinks it's super cold outside and compensates by dumping tons of fuel. No way, never ever 20HP on our engines...maybe 2HP at best. Gas milage will drop about 10-15MPG.

/use to build 'em
//they are a joke and will totally fu*k up the sparkplugs after time

Too Slow

 

if it costs 5 bux..its krap.
