What’s fuel pressure? Taking for granted not using the same fuel pump from the VP setup...
Are you using the same boost gauge to test for leaks that you are for running down the track?
I use a schedule 40 pipe cap on the turbo inlet for my boost checker. I use a a CTS for boost and have an Isspro boost gauge plumbed in for drive pressure.
That fass must work well. My AD200 would hold 60 at idle but Wot down the track was dropping down to 20, ended up going to a waterman.60 at idle and about 50 down the track. Use a FASS 220
Is the CTS reading boost from the factory MAP sensor? Or do you have an add on electrical boost sensor for the CTS? If it is reading from the MAP sensor, I believe it won't read more than 36psi.
I ran into a similar issue with a CTS monitor when I ppumped my old 24 valve. The CTS would read accurately until 36psi and then top out, while the mechanical boost gauges I had would read all the way to 80psi.
Maybe try verifying boost with a temporary mechanical gauge just to eliminate the CTS.
Are you 100% sure that you are getting full throttle travel out of the linkage.
I've had the same exact experience with my AD200...what do you do for fuel filtration?That fass must work well. My AD200 would hold 60 at idle but Wot down the track was dropping down to 20, ended up going to a waterman.

Ran a inline fuel filter, one of the cylinder ones dont remember off the top of my head. I think it was a 10 micron?I've had the same exact experience with my AD200...what do you do for fuel filtration?
