But if the GT3071 is less responsive than a T34.63 and I would limit the boost, what's the point of having the GT3071? I'm Stu would be able to do a safe chip, but it's probably less optimal than the T34.48 chip, as that has been done many many times.


I know a live map would be best, but I'm from Holland so that isn't easy. There are a few people here who can map the Weber management, but none of them do the closed loop fuel control that I really want to have.


So I still believe a closed loop, off the shelf chip for a T34 is my best and easiest option. It's a bit of a shame, because I know the GT3071 live mapped and running full boost would be much nicer. But I'm coming from the standard T3, which is only running about 1.2 bar since it doesn't have a 360 degree bearing, so going to a T34 that is able to run full boost should be quite an improvement already.
