Have had the td04 in now for about a month (been taking it real easy on it to make sure didn't have any other problems first) and have found that the turbo does seem to boost at a higher rpm then my stock t25 did, but I am only get about 7psi in each gear (lower in 1st and 2nd around 5psi). I have not done anything to the ecu yet and still waiting to get the dp but can't figure out why the dramatic loss in boost???
