Here's another varible I installed silcon hoses for looks in some areas including my controller jumper. My boost increased I've gone a full turn counter clockwise and I'm still carrying 10 lbs with spikes to 13. I also have a working A/F now and when boosting I'm yellow as long as I'm in the throttle .

I had wondered before about the hoses, and what would be the effect of changing ID of the hoses. It is like a river compared to a canal; the relationship between volume and pressure. If the volume is increased, the pressure is reduced.
I have already questioned the 1/4" hose that feeds the WG solenoid from the MBC, which is fed with 1/8" source. If the larger ID hose delays the pressure from arriving at one metered (sensored) point as compared to another point that is sensored to monitor the other, the time delay could also introduce error code potential.
If you are trying to move 14 PSI of pressure through a hose with a 1/8" inside diameter, the pressure coming out of the other end would be closer to the input pressure than trying to move the same pressure through a higher volume hose (one with a larger Inside Diameter).
This assumes that the pressure is not constant. A increasing and decreasing pressure would be more likely to be affected by increrasing the volume of the hose delivering it to a monitoring or performance affecting device (sensor / wastegate solenoid / TIP Solenoid)
While the silicone hoses may have the same ID, they may expand less under pressure, and deliver exactly the same pressure that is fed to them. On the other hand, if they do expand more under pressure, sending a lower pressure to the wastegate solenpoid or TIP would result in less venting of boost.
What we need is a cable with logic that would allow us to use a laptop to log actual sensor readings that the PCM is reading, and software to convert those readings into real-world figures.
I know there are fairly inexpensive data loggers out ther that allow you to log as many as 4 or 5 of the parameters and download the info to a computer later. If the data logger has a computer hookup, it should allow the laptop to monitor under dynamic conditions. Now, all we need is software that will interpret the results.
Whitney sells the Data loggers for $139.00 and $170.00. Maybe I will get to splurge when we get back from this cruise we are going on May 10th. I know it has cut deeply into my "play money" potential...
