>Buddy's K7 has a power commander 5 with "we have no idea" tune loaded on it
>Hook his PC5 up to my laptop, run the PC5 software on it and look at the tables
>Only has a fuel table, no ignition mapping changed
>Seeing lots of negative in high rpms and other weird areas
>I'm no professional tuner, but it doesn't look good
>Look at power commander's website
>They have a loadable fuel map for his exact setup, full two bros system, aftermarket air filter
>Load up tune
>Lots of positives and not much negatives, looks safer but not necessarily better for power gains
>However there's a massive 80% fuel dump at 8k rpms
>Again, I'm not a tuner, but I know a thing or two, and looks really weird
>Second guess myself
>We decide to try it
>After all, it's from the power commander website, right? It can't be dangerous, right? Right?
>Save his old map
>Load the new map
>Go ride
>Shooting massive fire balls everywhere, and bogs and won't rev past 8k where the huge fuel dump is
>Sounds kinda like a rev limiter but fucked up and dangerous for the motor
>Dumping so much god damn fuel the engine physically cannot rev past 8k
