finally just got it done!! I went through three electronics before I got one that works but the truck is running like a top! programed right and now making fords whistle sound like ****! after messing with it long enough I got it run the way I want it.. at an idel is screams with turbo closed 100% and when I take off it opens quickly so I don't have much smoke at all and I spool about 10 psi right off the line.. I'm about 30 psi by 2000 rpms and im pushing about 45 psi at 3000 rpms. if you have not got it yet don't loose hope its so worth it!! my truck sounds like a jet and I don't let out more then a haze of smoke from 1500-3200 rpm with 100hp sticks and a 180hp Quadzilla!!

Scott, if you can send me a screen shot of your table. My psi only gets to about 27-28. Id like to see how ours compare. Dyno'd the truck and made 375hp and 750tq. I know it sounds awesome at 100% closed but that makes your EGTs stay high when ideling. I have mine set to about 10% closed at idel so it cools down faster. I am also finally adding a PDI manifold and going to try out an hx40 compressor wheel.

I have a couple problems with that.. one I don't want to plug my box in because last time I had it close when I plugged in the box with out programing it it changed the way it ran... two my turbo is not timed like yours is so when I have a setting to 130 its like 60 percent for me.. now im not sure if that the real number... third problem is I manual control the bottom end... so what I do is set the truck at about 10 percent and when I take off I open the **** all the way allowing the turbo to do the rest of the work.. this prevents me from having my truck reach really closed numbers while driving.. so my vgt range is from about 1500 up.. I have a manual so the problem I would have is if I got it for a good take off I was to closed when I shifted.. so I fixed that.. btw make sure you check your gauge.. I have two in my truck now and the adrenaline and the manual gauge both read true of each other.. I say this because I can hit 60 psi with this turbo if I close it up just right but the manifold pressure I can only imagine so I don't tend to do that..

My truck is a manual as well. I have tuned mine to give me good spool with minimal smoke. I think this setup would work better on an auto matic. To work idealy in manual there really needs to be a table set for each gear. Why isnt your turbo "timed" like mine? Does your programming table have different software? My drive pressure gauge will read almost 60 when I get it on it . The new manifold has helped bring that down. Whats wrong when you unplug your box?
