Are there any good performance chips out there on the market for my IS? and if so where can i find the best one. I have searched everywhere on the net and cant seem to find one. Please help and if anyone already has one can u tell me if it is worth buying??? Thanks alot!!

 

i"ll try and be nice

There are no chips for the IS300...This isn't a German Car

 

Crazy G is right. Before you ask any questions for "performance", try using the SEARCH function and do more research. When you're question options are spent, then post something on the boards. There is no such simple "chip" mods for any Toyota or Lexus. Toyota/Lexus ECU's are well engineered for performance/efficiency that theres no need for such things. Bottom line is...do more research.

 

can we be a little more rude??????? i mean damn, i tried to research it on CL and could not find anything. I'm new to this forum and i just got my car so I was not sure. Sorry I dont know as much as u guys. OH yeah and way to make a new guy feel welcome!!!!!

 

flipside that was not meant toward u. sorry if it sounded that way

 

calm down guys. mullet, don't worry, i am sure the other two members are out of good will. i know flipside909 personally and he's a nice person, he definitely didn't mean to bash you in any way. we are all trying to help out each other here

 

Forget about chips. You're better off driving the car the way it comes from the factory...for many reasons. The engineers know what they're doing. When you start screwing with sensors, spark timing, engine temperature, fuel flow, etc..... things start to get messed up. The warranty could be voided, and even worse, engine damage. These engineers at the factory don't make big bucks for nothing.....it takes a lot of time, work and knowledge to properly design and program an engine. True, there are tuner companies like AMG, Roush, etc.....but even those guys are professional engineers that know what they're doing and these companies are linked with the factory, and the factory warranties their work. The factory will NOT warranty you screwing around with aftermarket chips, and you may not pass emissions test if your state has them.
