There's quite a bit of arrogance floating around these forums. I'm finding it best to just ignore it.

 

You mean general ignorance, right?

 

So any one have any info on a real performance up grade !! Chip / program or something.

 

Ive got the mapecu3 on the way from New Zealand right now. I'll be running it in open loop mode and should be able to fine tune fuel and spark above 60% throttle.

Its kinda pricey but I think it'll be perfect for my NA tune now and later I'll just need one additional piece to run it on a supercharger setup too.

check it out www.mapecu.com

 

Do you mind giving me some tips. I just got a 2006 IS 250 RWD with 47k ! I would like to get more power and some LED lights for interiour front head lights and back brake lights. Car is dark gray! Help??[/QUOTE]

 

well the real problem you wont be able to solve is that you've got the is250. I'm not tryin to be rude but there just isnt much help to be had for that engine.

 

Step 1. Sell your car.

Step 2. Buy an IS350.


That will add significantly more power, for significantly less money, than literally anything else you can do.

 

Instant HP for you Lexus IS!
