The unit is up and working and a variety of calibrations are installed.
I'm running a VDH5 Box code with a TNA7S3 conversion But the recommended is TNAA4S2 (running these calibrations currently). What is the difference between the two?


Secondly I notice many calibrations have 2 with the same description, are they usually noticeably different or just slight variations?


What is the differences in the 120hp Extreme and the 120hp Race?


For those running mostly stock (4" exhaust, S&B intake) as I am which is better fuel economy: 65Hp daily driver mileage or 80Hp daily driver mileage. Guessing one may be a city and other highway version?


What high idle calibration do you all recommend for warming up engine in the winter prior to driving?


Lastly is there a forum that discusses the PHP calibrations exclusively, if you have a favorite please point me in that direction. I'm kinda hoping to find some calibration descriptions, past the generic labels.


I know most of these questions will be specific to my PCM code but guessing most of the stock calibrations are going to have similar results, and looking for the ones that people here liked.


Thanks!
BTW Painting the ribbon cable black helped appearance when surface mounting!

 

I running Gearhead tunes so I don't be much help. In my experience the MPG is the same in all tunes w normal driving. It changes when mashing the throttle in different tunes. This is due to the availability of more fuel. I could drive in my highest power tune and not know it until I stomped on the pedal....unless I was towing then the egts might get too high.
