HPX Results (With AE Data)
I got my HPX from Clay at Riffraff Diesel last week. I installed it and immediately said "wow, this is different."
I was prompted to purchase it because my idle was a little rough, and after getting my hands on an AE discovered my PERDELs were high, but not nearly out of range. Even number 8 was behaving.
So I dropped some cash on the HPX and decided, what the heck,
After installing it, I knew something had changed. I even told another member (acf) as I was doing an AE run, "I dont care what the data says, its better."
Well the data backs me up. The AE is showing substantial reduction in HPOP pressure spikes.
I have attached a graph from the idle test, as well as the data exports from both before and after idle tests. Unfortunately, due to varying road conditions (even on the same stretch of road) the 55mph and 70mph runs were both inconclusive due to several anomalies in the data that rendered them useless.

that's pretty cool to see data that backs up seat-of-the-pants. My idle is smooth but since I did the FRx and HPx at the same time, I did not know which contributed more. Hutch mod helped even more. I often wondered if the HPx was doing much.

Awesome! This has been on my buddy and I's list for awhile now! Glad to see numbers that will make the purchase worth it!

Good work Trey. A lot of the HPx has been known in theory for about 10-12 years. This just puts data to it. Thanks for posting up.
