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.
its entirely upto you mate im just pointing out the option I would take.
and I don't believe for 1 second that a gt3071r is less responsive than a t34 0.63.
ive run a gt40 on a 2.6 at over 700 hp and it was more responsive than my old 500 hp yb on a t4, if its available roller bearing I would want it, if you want maximum response go with the smallest turbine housing you can get which is 0.63 I believe, or find a t34 and just fit it just seems a waste to me as you've got to spend anyway so may aswell upgrade while your replaecing it.
