I am interested in improving my IS 250's performance by using a performance chip. The dealer said that this is the best way to improve the cars performance. Does anyone know of any websites, people, or places where they sell these for the IS 250?

thanks

 

I don't think they made one for the IS yet.

 

there arent any chips yet for the 2IS, your best bet is the usual intake/exhaust combo as of right now

 

Save your money. You aren't going to get much more performance out of the 250 engine. You can improve the sound quality of the exhaust, but that is about it.

Want more performance? IS350 or IS-F.

As usual the dealer doesn't know squat.

 

^^^^ I agree

 

If he can sell it, he'll do his best to sell it...
