Hey it takes quite a bit to get a 6.2 with a whipple or maggy to get to 550-600 HP
Then you see a vid like this and go really? I would like to her opinions if this actual or BS or somewhere in between.

What gear, locked or unlocked. Probably locked.

I would say that at least 95+% of the time Chuck tunes vehicles for e85 only. That adds a little.

And it also depends on the mod list. Headers, studs, pulley size, cam/fuel lobe?

I would think with that number, it's 12-14psi on e85 and some fat timing.

Safe? /shrugs

Get you a ls3 top end and see what happens.

I wouldn't doubt it. Paul from magnuson told me he was an injection pump swap away from 700 with his 5.3. It's got to be an E-85 tune and did you here it lope before the pull?

647/591 was the last post I saw.

TTRaydo made like 650/600 with a one-off twin kit but spit a rod out the block not too long later. I suspect tuning/fueling on that one tho.

Yup... 6.2's are junk. Should all run 5.3's cause they rule the interwebs and that pathetic joke of a "performancetrucks" facebook page lol. Realistically a 6.2 with a cam, pump, injectors and then boost should do better than that.....
