Welcome to FTE!

Where did you get this "chip"?

 

Welcome to FTE, buick40.

I'm moving this to the 5.4L V8 section, as it should get more specialized attention there.

Any more details on the chip? Who made it/what brand is it, where you got it, etc...

 

dynamic tuning on ebay

 

the chip is made for power and mileage.it only has 25,000 on it some say it dosent have enough power but weve not pulled yet. it does have 9200 gv thanks

 

Contact them and ask for instructions. Sounds like some kinda scam product to me. kinda like the resistor in the temp sender to fool the pcm into thinking that the engine is cold and runs it rich.
