Got the hybrid on a week and a half ago and have put over 1000 miles on it getting to know it. It is definitely a different animal than the A Team. Boost comes on more quickly, 5psi by 2000rpm and 10+ by 2500. If I stay in it long enough I can get 18-20psi on a shift. Smoke clears up quickly, little to no visible haze at WOT compared to a visible haze from the ATT. EGT's are a little cooler, really won't go over 1150 unless you push it hard. Otherwise, it is mostly 600-1000 driving around normally. Doing 72-75 on the highway, about 2200rpm or so, its 5psi, 750-800*.
Butt dyno tells me it pulls harder than the ATT does, however speedo says they are about the same. Which I find to be interesting. Spec-wise the hybrid is the more capable turbo on paper, but for some reason that darn ATT pulls just as hard. 0-60 time is still around 10-11sec. I don't think my trans is helping that very much, seems like the shifts are starting to get a little lazy. 205k on the original tranny, cant complain. I think that my tune didn't play very nice at WOT with the ATT. I could get 11-13psi out of it, but would still get a good haze at WOT. I am not sure if the tune is commanding more air than the ATT can supply, or if it was a timing thing or what. In any event, the tune (which was originally written when I had my HX35) works pretty well with the hybrid. I think the hybrid can DEFINITELY out perform the pump/tune combo, which means I have room to play with more fuel.
I took the truck to the Cape last week, and did an MPG test going up (like always). Last year, I got 23 with the 35, tune, intake, exhaust, yadda yadda. Same trip, same driving, same mods - except with the Raptor 100 - truck got 18.5. I notice the fuel pressure is down a bit, and I am thinking that since the hybrid moves more air than the 35 that the truck is using more fuel? Just a theory. In any event, it lost some highway MPG which kinda bummed me out. I will retest though, as 5mpg seems too significant to be true.
All in all, I am happy with it so far. I am interested to see how it responds to more fuel. I still have the FTB fittings to add, as well as my 1/2 fuel line setup, remote filters, etc etc.
