I know a few of you on here have gotten the tuner from hemifever. I have also read about it on other forums. Does anyone here have any before and after numbers
as far as horsepower and torque are concerned? Also my truck is a California emissions tuck but I live in Utah so it only has to pass Utah emissions standards.
Will it pass if I end up purchasing the SCT from hemifever?

I live in Utah and registered two months ago with the 93 octane tune loaded with no issues. As for before and after #'s. It is difficult to tell without a
true dyno, and your results will vary based upon your gearing and other upgrades but it took 1/2 second off my 1/8th mile time, and if I can ever get clear
conditions to work with lately it would be fun to test some more. Since we are both in utah we could reset mine to stock and do some same day before and after
tests. But the weather must clear first. My truck has 3:55 gears until I find the right guy to change to 4:10, that has affected my results a bit.

That is a very generous offer, and I appreciate it. I doubt we will be getting that type of weather anytime soon. Did you get the custom tuner or the can/as is
tuner? My truck has the fastman throttle body, a drop in K&N, a JET chip and just recently (this month) a brand new exhaust system. It had a new cat that
was modified to accept a 4 inch pipe welded straight to it and all the way out through a free flow muffler and a 5 inch tip. So far I think my exhaust is where
i have noticed the biggest difference. I can't wait until summer so I can see how it does with pulling my trailer! I've really enjoyed playing in the
snow with it. I'm not sure what gears I have in my rear end, I need to crawl under and look. I know a guy in Ogden that restores old cars and builds
engines. He does really good work, if you want I can get you his number and I am sure he would do an excellent job on your gears once you are ready for a
decent price.
So are you happy with your hemifever sct purchase so far? Being in Utah what kind of mileage do you normally get out of your V10? Did the tuner have any effect on the mileage? Thanks for the help! I am very seriously considering making this my next purchase, I just want to make sure that I will be happy with it after I spend the money on it. I plan on doing a lot of engine work to my truck over the next 4 or 5 years so having a tuner would be nice if it works as advertised. So far I haven't seen anyone that is unhappy with it. Jackie
