Has anyone tried one of the $34.95 "Ultimate Performance Chip" being sold on Ebay. This one does not interface with the ECM. If so, is it any good?

My 99 had a Hypertech program on it when I bought it, and the GEM got messed up.

I would like to get a little better performance, but not spend a lot.

 

Without doing any research to find what you're talking about, I'll go out on a limb and say it's probably just a 10k mod that you could do yourself for $2 and a trip to radio shack.

 

I've never heard of anybody getting one of those but I had a SC tuner, of course thats before I found FTE. IMO, save your coins for a reputable chip builder here, you can get a nice chip with some stardard tunes programmed just for your truck and won't break your bank plus mileage gains.

 

It's not a chip, it's an ICP sensor fooler. Nothing more than a resistor.
