Hi all,

First time posting on this forum. I've been the proud owner of an '06 IS 350 since April 08. I have nothing bad to say about this car. I simply love it!! However, while recently getting an oil change at the dealership I made the mistake of test driving an IS F. I only call this a mistake because now all I can think about is how much FASTER and responsive the IS F is than my 350. As I am not in a position to upgrade 30k in my vehicle currently, I'm looking for ways to make my 350 faster. Does anyone know of a good performance chip/package for the IS 350? If so, does putting something like this on the vehicle void the warranty? Thanks for any words of insight.

There are no chips and there aren't presently any ways to make the 350 really faster.

Sorry for bumping this thread up Don't waste your money on these. I was thinking about getting a performance chip too, but it looks like these things don't do crap. I was reading this article about it, and it looks like these things don't work at all

We knew that already. If someone really wants to fool the temp sensor just get a 50 cent resistor of your choice.

Lexus has the F-Sport line of accessory add on's for your vehicle. Brakes, exhaust, suspension, cold air intake etc. Kinda pricey though. You can Email me if you want more info on them.

We have posted here and it's available on Lexus.com and sewell lexus.

Chip is encrypted.

Good article, but I wonder if still people buy these junks
