if the clutch was changed they may have forgot to bleed the attesa when they put the box back in.& sorry yeah the attesa was fine prior to the work. All green, all ok. No reason to think it has gone weird on me. New clutch as well, feels great. New 265 profile tires. Ohlins.
I should have spent some more seat time, try WOT in 3rd or 4th, watch the torque meter and PSI hold. etc. But tuner said, yeah it sucks doesn't it, lemme work on it some more (it has been weeks already) and try to calm down the valcon. When I got the vcam it CAME with a sheet of recommended settings for 2530s with bigger exhaust cam. I ASSumed it would be bolt-on. makes me wonder..
they said they tried it running on the stock (hks) wastegates, no boost controller trying to do anything, and it was still the same issue.Having sealed off wastegates however, will produce exactly the effect you describe.
Dunno man I guess I have to drive back and take it out for a more extended test.btw, how much is "everything" when you're talking about your boost? If it instantly hits 15psi and then stays there locked in, congratulations!
