That TPS issue is what's holding you back, and if they can't figure out a fix to that,, you should grab your wallet and run away. It's a simple fix just like what Tom said...

307whp on 22psi, sounds about right. And on E85 you'll probably looking @ 380 - 390whp. There is no way you can make 400whp with just those Mods you listed....

 

fair enough whats next on the road to 400 hp.....

 

Upgrade to a stock frame turbo like a BBK or FP and you'll be well over 400whp on E85.

 

To get 400whp on their Dyno, you'll need a test pipe (its not on your list) with a free flowing exhaust, some ARP headstuds, a stronger fuel pump than the walbro 255 or bigger injectors, a high pressure wastegate to hold better boost up top, and 30+ psi of boost....

Unless your car is one of those Factory Freaks! You might get to 400 or close, but will run out of fuel @ 6k rpm. LOL

 

ok already have the apr studs and 255 fuel pump so Ill get larger injectors( i currently have 1000), and fftec will tune it to 29/30 psi on e85.....depending on the number of knocks (more the 3 knocks and they'll turn down the boost)

 

should be able to get 400whp on that setup, fairly easy.

 

On Dynojet yes.

 

what the hp changes for a mustang dyno vs. Dyno jet Dyno?

 

How much do u think id make on an 06 Mr with fp red coswoth m3 cars basic boltons stock block with 115k and e-85? Ball park?
