Fitted a TTE420 as my K04 that I reconditioned 6 months ago crapped out. It has the APR spring on it which requires 0.75bar crack pressure so I'm running full wastegate closed till I go update the tune tomorrow. Nearly crapped my pants when I saw the boost needle jump off the scale, I saw it around where 2.5 bar would've been, tops out at 2, LMAO.
Also got a MIB2 unit installed, which was a total bitch to code properly, had to get a new can gateway also for vcds be able to access it. Car play and all, too bad my Huawei doesn't support Android auto
The bluetooth is way nicer then the chinese dongle crap I had in my RNS510.
