Your buddies are fags. 
The industry standard IS DJ. But, that doesn’t mean it is accurate. Mustang dynos are notoriously low so how is that accurate? The fact that they are LOW mean they are inaccurate. It’s really hard to correlate trap speed with HP due to all the variables (not to mention peak HP is not the same as power curve). But, like I said, that’s not a bad thing. It’s hard to get a repeatable, accurate dyno. At the very least, you want repeatable because you want to see how the #s diff based on changes. I got lucky and got both accuracy/repeatable which, coincidentally, was a DJ. But, people DO assume HIGH with DJ. But, DJ is just the dyno but not the SOFTWARE/SETUP within the DJ. It really does diff from dyno to dyno but stereotypes exist for a reason. I just pointed out that not all DJs read high.
I don’t know anything about that dyno but 440AWHP in an EVO and 125-130MPH do not match, at all. Unless you took off the frame?
It could be. I didn’t go to the lot much.
LOL. Nicely played.
