Need some help with my JEEP!

[dunny_mark]

I was thinking of putting a chip in my jeep wrangler. They are on ebay and claim to give up to 20hp gains. Does anybody know anything about these chips? They all seem to be the same, claiming to tweak the air-fuel mixture thus making it richer and making more HP! It plugs into the AIT sensor and also claims to change the timing to run stronger and increase power.

Any help would be great!

Don't do it. Best case scenario it does nothing and you waste $20, worst case scenario you're jeep starts knocking from the
"chip" leaning out the fuel mixture to much and in 20k miles you need a new set of rings.:D It's worthless.

Dont buy it. All you will get is a piece of wire with a little breaker in the middle. You plug it in and jumt the two prongs together. Waist of money. A coworker bought one and brought it to work so we could all laugh at his stupidity.
