wkdtime Posted May 31, 2006 Share Posted May 31, 2006 Hello guys, Just a query that has me baffled, When a J spec TT is decatted fully, it over boosts to 1.4 bar+ this because the internal wastegate is over whelmed as it is too small, but why do we have some members on here who have gone full decat on J spec and only see 0.9-1.0 Bar boost (with no restrictor ring) pretty much the same as the UK spec, i know that two cars are not alike, but if the overboost is due to the small wastegates with the J spec's have, then shouldnt all the J spec TT's over boost when fully decated?

AJI Posted May 31, 2006 Share Posted May 31, 2006 do wastegates weaken over time? maybe the newer models (or models with a replacement wastegate) don't get the boost creep experienced with the older models? just a thought. Quote Link to comment Share on other sites More sharing options...
