    Pressing my luck!

    Tuning by Marty at Extreme Performance. 3.5" 6-bolt pulley from VMP and FINALLY a custom tune (had to get off the Roush canned tune). Still stock bottom end, forged internals will be coming in the next few months hopefully.

    1st pull at 20 degrees of timing




    Backed out as much timing as we could to 17 degrees, this is what we settled on




    The pull:

    Thanks man! I'm a little past the "safe zone" which is apparently 450whp. On the Roush forum, there a few folks running 490+'ish whp with the same setup as me and still running strong.

    I don't really beat the slop out of it so I think it should hold until I pull the trigger on going forged.

    The Roush tunes are notorious for running really rich and they are global tunes not really taking into account our 91 octane out here. There's also some weird safety parameters that are built in most likely for warranty purposes. They're not "bad" but not optimized either.
