I've been around for a while and I consider myself very familiar with boosted cars and have a 800hp 1GS3 in the works.
I'm curious what ems/fuel management you guys are running when you boost the 2nd gen IS250/350's ?

When they came out everyone was talking about how they were "un-boostable"

Being direct injection what are the issues ?

they're not "un-boostable", just "un-tunable".

I read one guy used a MAP Ecu which would make it remotely tunable unless you need more fuel.

^Yeah, I don't believe he has fully explored using it just yet. But as it sits now, S/C folks have been seeing 7-8lbs and there has only been one public member (IS250) that displayed his remote turbo setup. ~5lbs if I remember right. Others claim to have a turbo'd 2IS, but yet they don't share pics at all.
