I bet that was it. I have heard of those tunes that gave an extra 200hp, I thought it was made by Hypertech though?

On 5psi, this thing put out 410hp and torque was about 412, something like that.
Those numbers netted a 11.9 @ 110mph.

I finally got the intercooler in and my boost under control at a solid 9.5 psi (10psi peak). I was hoping for about 500hp
It made some nice numbers: 669HP@4763rpm / 744lb-ft/4654rpm


for instance, 5psi netted 410/412

then 5 more psi netted 669/744

thats 51.8 rwhp per lb of boost above 5psi, does that really make sense?
and 66.4 rwtq per lb of boost above 5psi.......

someone clear this up for me

I am not knocking the STS in any way. They do make power......

But is anyone seeing the 30 plus rwhp gain per pound of boost a little far off?

i need to apologize for my above post, my computer started acting funny so i hit submit and came to edit the post but it f'ed up again.
as i was gonna say he is one hell of a tuner and that thing has probably been tweaked 100 times BUT after watching all of the sts numbers and being no mechanic myself, even i find it a little hard to believe.
Just hoping for some more info.
sorry about the post i know it came off a little wierd!

I think that the numbers are alittle messed as well. There is a guy with a forged ls6 with a gt70,fmic sts car out here in mass and i made 620rwhp at 10# of boost. I is through a 6 speed and was done on a mustang dyno. I think that allens numbers are alittle high for the mods. But either way he still has the sheet to prove it
