Little update to this thread.
In my quest for more power, I removed the muffler/cat and it’s now 4” from the downpipe back with a straight thru diamond eye muffler. Noise is no different, spool seems a little better. I’m taking it on another trip this weekend to compare to last weekend. I also added a scan gauge so I can monitor EOT mainly. I already have analog boost/egt gauges.
I also am in contact with a shop working on tuning for the VT365. He already has a FICM tune that will work (I suspect the hyper max was only modifying ficm values). He has an econo tune and 40hp and sone bigger but will likely have egt issues with over 40.
Also figured out my ICP sensor wasn’t functioning correctly so I replaced that. I will see if the MP8 works any better with a good sensor, or perhaps the mp8 killed the sensor.
Other than the major lack of power compared to my old 8.1 super C, were loving the supernova. Drives way better, and much nicer once parked.
I’ll update as I get more tuner info if anyone’s interested.
