Hemifever tuners

Which tune are you using? 87 octane? 93 octane?
It woke up my 5.9 by quite a bit at partial throttle. I didn't notice a whole lot of improvement at WOT at low speeds, but any partial throttle at low speeds and WOT at highway speeds both noticeably improved.
It woke my wife's little 4.7 V8 right up in all areas.

Keep in mind these are tuners, they can only do so much.

after i did the hughes intake the truck ran great, from idle right on up. the money i spent on the intake was worth it. i did the tuner after the intake manifold swap. on the low tune, no difference expect my gas mileage going down which i did not like. i then ran the high octane tune which coat me a arm and lonf for fuel and gas mileage was still down and not much gain at all. the mid octune seems to do nothing as well with lower octane. i EXPECTED the programmer to do something.... i see no gains. wide open throttle i feel a difference since it revs higher but nothing else....
