Nice spec, power is stil dropping of bad though as peak power is still under 6000rpm.
Can you post up the other plots with boost and AFR.
Did Simon try anything with the AVCS to confirm it is working OK or check the cam timing was OK and not jumped a tooth.
I'm not suggesting Simon hasn't done his best, but just a thought.......
We found on Rob's Celica that the cam timing being slightly out made a huge difference to the top end power.
The previous owner fitted vernier pullies and had them set up by a so called specialist.
The lack of lumpy idle considering the cams that were fitted just didn't stack up and made us think.
Luckily the car came with standard pullies so Rob gave it to Vince to swap the verniers for the standards (it was cheaper to fit the standards then get the verniers fully timied up).
The car came alive after this and the idle was a little limpy, as expected due to the wilder cam profiles.
Your power just doesn't seem to match the Spec, especially considering Litchfields get 415BHP and probably run really safe due to the warranty.
