Performance Chips - The Mother Thread
Are there any chips yet for the IS350? A chip that gives it more horsepower and improves the gas mileage? Will they screw the car up at all?
Code:
Moderator Note - there are NO chips for ISx50 that do anything useful - this thread is here to bring all these threads into ONE place - any new threads will be merged into this one as well.

Chips on normally aspirated engines really tend to do very little for the money. If you want to chip a turbo you can get big gains. The cheapest gains offering measurable increases for a normally aspirated engines are generally intake and exahust. After that you get into hard parts which equal big $$$$$.

And no there are no replacement ECU's for the IS. Toyota/ Lexus usually hardcodes their ECU's, the only available reflashing available right now that I know of is done by TOM'S of Japan. If you can decipher Japanese kanji then visit their site. I was told that you send them your ECU and in 8 weeks you get it back- reflashed w/ different fuel curves and optimizations.

What are you basing this assumption on?

Sorry, no chip.

This is my question...
Can you tune an IS350?
Like a friend of mine went and turned his Mustang GT after he did some upgrades and he is getting 30mpg on the interstate, and he does a far bit of hard romping.
Or is that what the chip is?? I really have no idea.
