Performance Chips for IS250 ??? Myth or True ?
Anyone have any info on performance chips? I've seen the cheap ones on EBay, and know its got to be to good to be true( "Get what you pay for"), I also don't want to mess with the ECU w/o doing my homework in regard to performance chips........ Thanks

even if there was a performance chip, i think the gain will be minimal... i would get it too, but i would be afraid in the long run, might turn on check engine light LOL

theres practically no performance mods for an is250 without spending a ton of money. if you have a rwd, maybe headers, midpipe, exhaust that will get you about 15-20 hp more. Thats about it.

And I would think that would be mostly peak Hp...power "under the curve" would probably be not effected very much. Maybe 5-8 LBS/TQ.
