Last I heard, 3800 perf sells ZZP tunes, if this is true they suck

Intense, not certain there

DHP 1.0 is alright but there is better out there.

Overkill tunes kick ass, i'll vouch for that. I've ran a few different tunes from him in the past. Infact, my black GTP still has an Overkill tune on it...
