I know with the supras if you remove the cars you need something to control the boost.

The above statement is correct for Rev 1&2 but on a Rev3 the unichip can control the boost using the factory system

With the unichip in place, I had extreme overboost, up to 1.2-1.3 bar.This was with no form of boost controller at all.
I initially put this down to an overly free flowing exhaust system
(3" D/P and 3" exhaust) but having put the cat back in for the MOT, I still had the overboost problem.
Once Luke had removed the unichip I had rock solid 0.7-0.8 bar boost.
I can only assume that the unichip had a
"bad" map on it that caused the overboost
Slarty, the reason you are on low boost I guess is because your on spring actuator pressure only and no bleed by the vsv.this could be because the unichip has been removed incorrectly.
