Hello everyone,
I am working on a 2008 6.7 RAM (fully deleted, open exhaust, off road truck). With the stock file, the truck used to go 100% VN position at idle and light throttle a few seconds after start up. With open exhaust, it sounded absolutely amazing.
I flashed a delete file (Dimsport/Swiftec) to shut off emissions. Then I tuned the file for power with HP tuners.
My issues:
1- The truck does the 100% VN with Jet sound effects for a while, then it doesn´t do it anymore.
2- No boost maps on HP tuners. Is boost control logic based on MAF and turbo speed?
3- No VN tables. Just max Vane position tables.
4- Live data only reads 37 psi MAP.
My theory is that 100% VN position is part of the emissions system operation strategy. Can I replicate this with emissions off, and HP tuners?
Thanks in advance.

Using the minimum vane position table you can raise the values in the idle part of the map to force the VGT towards the position of your desired sound. I would suggest somewhere in the low 90's, as 100% is pretty tight.
Hope this is helpful,
Nick
Thank you Nick. I will try that.
What about the boost control strategy on this model?
