Has anyone tried this? What were your thoughts?

And before everyone jumps down my throat, yes I know ZFG is a better tune, but it's the optional engine warranty that grabbed my attention

The first thing is the drivel about 20%+ extra fuel mileage. That's a dead giveaway of crap. The car will use close loop fueling based on the 02 sensor which wouldn't be affected by this device. The racechip is a piggy-back system and works by tricking the ecu sensors into increasing boost and fuel pressure so it "can" enable more horsepower at WOT. But, it doesn't affect timing, so the increased boost is at the discretion of the knock sensors to retard the timing. I wouldn't touch it with a 10 foot pole, especially since you can get a much better alternative for only another couple hundred bucks. There's a reason they have to offer a warranty (and good luck collecting on it).

I read the fine print about the warranty, looks like you need to jump through flaming hoops to get it haha

Oh well, a guy can hope right?
ZFG it is.

Remember what Tommy Boy said about guarantees on the box! All they sold you was a guaranteed piece of shit!
