Hello Ford Truck community. I/we are stuck and hoping someone out there has the answer. I have been chronicling the build and then rebuild of my 2007 black Fx4 here on and off for years. This string has most of the highlights. The Truck started out as a dealer-install Roush stage 3 and quickly became a Mike Troyer special - with all the bolt on parts. 2 years ago, the engine let go and shortly after we rebuilt, the blower let go (likely not a coincidence). Through all the rebuilding, I have continued to run with Mike's 91 tune. The truck runs remarkably well for a tune on a completely remanufactured motor with a lower compression and a different intake / blower setup. I haven't seen an engine code since Stiegemeier rebuilt the intake and blower.
BUT....
Mike is off the map and his shop was a very long drive from Toronto. I work with a very reputable shop here in Toronto that does work on my 2011 mustang. They cannot get the truck to make any boost. Everything looks like it's working, but no GO. They keep talking about not being able to get the boost into the tables.
If you have read my posts, you know I am committed but not an expert at all. I spent a lot of time in Mike Troyer's shop when the first big bolt on build was done and I remember him talking about some "tricks" to get the blower setup working on an 07 but I can't recall any of the details. The shop I am working with has spent hours on the phone with SCT and Dyno Bob was also kind enough to take a call. Other than manually holding the waste gate, no one has any ideas.
Does any of this ring a bell with anyone? Any suggestions are greatly appreciated.

 

Once over 15 to 20 MPH, the underhood heat becomes a non-factor and the air intake temp is within a couple degrees of ambient, so it really only affects slow city driving, lots of idle time, or being stuck in rush hour traffic.

Generally speaking, it's a non-factor.

One of the biggest waste of money I ever spent was having Steggy port my blower. It actually reduced my ET's at the end of the track. I know they have good results with the Cobra's, but back in the day, it was a waste of money to port a Gen 2 L blower.

No idea's, but referring again to that time defined as "back in the day" SVT Performance, Lightning Rodder, and NLOC were the main Lightning tech forums. Check them out and see if they can get you squared away.

Long, long time since my last post. Long story, but my old truck was put into storage for a couple of years while I had a company provided RAM - yes, I drove a RAM for almost 3 years. Loaded up, beautiful truck that was very luxurious but when the time came to buy it out or hand it back - I gave it back. Nice ride, very little personality and I can't imagine what servicing that truck would be like when the warranty is up and the 7+ CPU's that make all the trick work start to get finicky. Anyway, I did it, I tried the dark side - it is a nice vehicle, but I remain a Ford Truck guy. I bought my old F150 back out a little over a year ago and she's been driving with limited duty to the hardware store or local transfer station but not much else. When I first brought her back out, I did book a day with a tuner where we had some success making power, but never achieved good drivability with the power. The truck pulled 450 / 640 to the rear wheels on the dyno, but would hesitate and stall at low RPM. This problem continues to this day - we mitigated the issues a little and she does not stall anymore, but power is down and low RPM hesitation is still an issue. We are sure she is running very rich. I am in Toronto and have not been able to find any other shops willing to tune on the truck. I have invested in an HP tuner and I've started to play around a little on my own - mixed results so far. I would prefer to be working with a shop but learning on my own is fun as well. I am looking for any recommendations regarding a Ford 5.4 SC friendly tuning shop in the GTA or willing to work remotely with me. Alternatively, if there is anyone reading this with a similar project using HP tunes and willing to share what they have so I can compare and learn, please ping me directly.
It's been nearly 18 years since I first bought this truck. The body is showing her age (aren't we all) but I've kept the go fast parts in near new condition and she still brings a smile ever time I go for a drive. The rust on the outside, just helps me hide what's inside.
