466/583 stock turbos....

FBO, jb4, e85 blend, 80k stock abused turbos (shop car), rb inlets, our modified back end flash (mhd)

Powerband is crap but numbers are cool

Wgdc never went below 65%... This was all they had to offer....

Dyno graph looks really good considering the garbage others have been posting. Nice and smooth... Great work on the mapping.

Can you post up the log? Would like to see the wgdc and timing. Thanks

Hpfp only tanked a little


The timing is fairly conservative considering most of the "protune" crowd here likes to do 15deg across the board :P
15deg at 14psi isn't much at all

True, I do like the curve you did to support the ridiculous boost levels. I bet that car is a blast to drive, those poor turbos lol.... Time to upgrade!

Lol! I've seen worse logs. It's really not bad. Hpfp tanking at low rpm looks bad but once you disable the code and tune around it, really isn't a big deal. Tanking at high rpm is another story.

Ballsiest dyno I've seen in a while!

. Thanks. And yeah HPFP was replaced after the dyno to keep it from tanking at max torque.

Car has ~5k old 335is/V8 clutch which is holding somehow still :P
