torque is 314 fflbs but bhp is down, what could be the cause??

That's one hell of a torque curve! Your horsepower curve is flatter than your torque too.

You happy with this? How does it drive?
 
could be i have same mods as you and am getting it rolling roaded tomorrow so i will let you know what i get, do you have Pace or Forge FMIC
 
Well, obviously the torque curve is dropping off too quickly.

HP = Torque(ft-lb)*rpm/5252 (Notice the curves on your graph cross at 5252 rpm)

So to get more HP you have to keep the torque up as the revs increase.

When you say BHP is down, compared to what?

Pure speculation, but I'd guess the remap isn't matched to the induction modifications. You did say you'd built your own FMIC - was the remap custom-matched to that?

yes been out and was remapped to what i have, i have read it could be down to the TIP as i have/had a standard TIP and this closes in on itself at 5000 rpm,

when i say bhp is down i mean as in a standard lcr narmally chips to 265 mine should be a little more, however i have been talking and some say the graph is not accurate as the loading was incorrect, and it was done in 3rd gear been told it should have been 4th
 
It should be done in whatever gear is closest to 1:1 ratio, which is usually 4th on a 6 speed car.
