Lexus IS-F Aftermarket ECU

For those of you that have been looking to tune your IS-F with a chip, you are going to be disappointed. Many of the competition, including the M3 have aftermarket chips available to increase the acceleration of the car. Unfortunately, the IS-F ROM can not be overriden and you will have to be content with the stock chip. Maybe this is not such a bad thing? We know there are stage 3 chips out for the BMW 335 that will actually put it up to the same speed as the IS-F! That seems good for the BMW, but in actuality the wear and stress caused by this chip will significantly reduce the life of the vehicle. For induction upgrades such as a turbo, you can add a piggyback ECU. In the end, you are still adding a ton of stress on a vechicle that was designed to be naturally aspirated. We understand you want to tune your vehicle faster, but any modification th the engine is going to cause stress, and it's just not a good idea.If you are concerned with speed, you could have bought a faster straight line vehicle. If handling is a concern, you can always lighten the vehicle and adjust the springs. Stick with modifications such as exhaust, headers, and intake before you consider any internal engine / computer modifications. Your are less likely to run into warranty problems this way. Yes, the Lexus terms state parts are warranted unless the modification directly effects them, but you do not want to take the gamble. If going 0-60 in 4.5 seconds is not fast enough to you, you are most likely a very important individual or should consider a new profession, such as driving.
