Car is vvti TT6. It's been off the road for a little while, whilst I do some work to it, fitting BPU parts. The only one that should have made any difference in I've fitted a CW FCD. Cats are still in place currently.
Doing pulls in 2nd or 3rd gear seems pretty normal, both turbos coming online as they should and making ~0.8bar boost.
However if I try this in 5th or 6th I noticed boost increase to 1.2bar (where I let off). I thought with the restriction of the cats still in place this wasn't really possible? Obviously I'll be taking it easy until decats, wideband, BC and fuel pump are fitted but in the mean time, what's happening?
