Those are some pretty good results, but like most other people on this site I only wanted, and got, enhanced speed and pull over the stock Ford settings. I'm not racing the truck, and I'm not making money at the track so the SCT tuner and files have given me all I need. I have a Dragy on the way so I'll find out how much better than stock the SCT tune is, and that's that. I won't spend money on an intercooler, springs, or anything else after this, although I did install the AWR diff bracket.
Another point is that I feel the ZFG tune with HP device and combined with the points thing is not something I would have, or will choose in the future. And to install a Whipple cooler for the sake of a few tenths is border line wasteful, UNLESS you intend to drive competetively in order to bring home the bacon. I have the money and it would be easy for me to build a very fast ST, but why? Probably just for fun.
And what the hell are points anyway. sounds like ZFG has found a way to make money for doing nothing. You pay for the device, you pay for the tune, and then need points. Sounds like BS and I'm glad now that they never replied to me when I was buying my tune. I own my tuner, it came with a great tune, and there are plenty of other companies out there providing custom files for the ST for around $175 if I wanted one. So who's to say there aren't files just as good as the files from ZFG at a much lower no points needed price.
Anyway, I have what I want and need at this point. The Dragy is on the way, I have a few appearance items installed and on the way, so and I'm happy with the results. Special thanks to the staff at SCT who have a phone number to call, people to return calls, and a super great all around product for $325 complete.
