AFAIK

the ecu on the lexus can not be cracked

you can have a airfuel tuning piggyback system to help the ecu

but the ecu will shut the piggybaack out after a while

so at the moment No

though

Toms 2IS line up is apparently already pretuned from factory which means it had some sort of custom tuning done from the factory

second what ilvs said above. i looked into it a while ago and nothing was available 6 months ago so unless things have changed since i'm not sure.

to my knowledge the most hp gained is from a set of extractors, other than that it's just the usual supercharger or 350/F routes.

It's a shame that Toyota locks either ECUs so hard we can't play with them. Even back on the old Soarers the only way to tune was to get a PowerFC or other (proper) piggyback ECU like the eManage or FCON.

I doubt it'd be much more than 15kW, hardly worth the cost in my opinion.

The engine is pretty highly strung out of the factory, with very little leeway for decent modification without spending 5 figures.

Compression is way too high to do anything decent with it apart from intake & exhaust.

how much more power would you get remapping ? what about getting a unichip ?

please read the above post

remap cannot be done

as for the unichip it might work

it might not

there are few supercharged IS250's in the US

AFAIK they do not run any sort of ecu at this stage

though the ARMA supercharger runs a ecu (their own) but i havent seen the damn kit yet so i cant confirm it
