I just ordered the quadzilla ZXT for the 04 in my sig. Wonder how she will do?

 

i liked the xzt on my 05 when i had one. almost went back to another one... you could just make out that you had an additional 60hp, that 60hp firmed up the tranny shifting though(when mine was stock). also, the boost fooler thats installed on the chip is pretty dang good- took my boost upwards of 40 psi, which is about 12+ over stock. mpgs sorta went up with it, but not much either..

 

Good luck with it.

 

I have had mine for over 2 years now and I am very happy with it. I did not want anything with more power because I tow heavy so much.

 

Had mine for 2 years now and I'm very happy with it. Also the best customer service.

 

Life as you know it, just changed!

 

x2 mite be a better choice as its updateable and shift on thhe fly.i like mine.
