Hi all.

I have recently had the Fd set up and when i received the Print out i noticed the Torque Curve sort of Drops off between 4500 and 5500 then Picks up again as the revs increase.

I am not too clued up on Dyno print outs but from what i have seen this looks like i have an issue or a Fault as it still does it on lower boost (its not very clear but big red line is 1 bar and just under it is a Yellow line which is 0.8 bar the lower lines where on a Different IC that was holding it back but the dip is still there)

A Basic Mod list:

PFC with Profec B2 Boost controller
Mild Ported Motor with 3mm seals
Hybrid 60-1 turbo (.96 hot side), HKS Divided manifold, 50mm WG
3" exhaust (decat)
Stock Primary Injectors and 1600cc secondary’s, Aeromoive FPR, 044 Pump
WI Injection ( 50/50 .6mm jet by the Throttles)
HKS Twin Power (10's and 11's Plugs)
Blitz FMIC

I was told by the Dyno operator that the dip was due to poor gas flow through the Manifold, but i have read that if the manifold had reached its peak flow the Torque wouldn't climb anymore?

Can anyone enlighten me as this is an Area i really know little about?

Thanks
