can someone explain me why Tuffy turbo pressure decresead
that's a hell of a claim.Just to add... My mate works for an engineering company who do quite a few 20v big turbo builds
They've seen greatly improved spool rates from swapping just the exhaust cam for a NA one... He said spool was literally 1k earlier on some of the big turbos

can he provide proof?

dotn be sorry its good to hear everyones experiences and to clear stuff up.Fair enough... Sorry, I was by no means discrediting anyone else's research! Merely recycling second hand info...
I'll have a chat with him about it next time I see him anyway. . . See if he has anything to add!

lupo has n/a inlet cam as part of its mix of bits
Ok I have an update. I scrapped the ADR cams and got a set of agn cams. Fitted them and reset engine codes. Car has a what can only be described as a weak idle but still pulling 22 on the vacuum gauge. There is a horrible flat spot bang on 5000 rpm then it clears and pulls hard. No matter what gear the flat spot remains. Boost is the same at 25,psi. No timing corrections and AFR good. I advanced the timing 4.5 degrees via unisetting and again no timing corrections. Car feel urgent off boost but flat spot ruins it. Going to try just the exhaust cam next

vvt car?
depends on what you want, but, precisely my point in this caseDont want increased overlap in a turbo application though?
