I just bought my Lexus GS350 f sport and it is L/ cert. I was looking at possible performance upgrades that won't void the warranty. I found this chip on amazon that claims great performance and fuel economy, it also claims it wont void my warranty. Can anymore shed some light on possible recommendations?

This is the chip I found:

 

I would not trust anything that says it's going to give you more horsepower (+35 hp) AND better fuel economy (+5 mpg). In fact, with this engine and its locked down ECU, I wouldn't trust anything that says it will give you more horsepower OR better fuel economy.

 

I dont know about that , I would stay away from it, too cheep and no reviews, there is this one company who is working on one RR Racing and they might do a supercharger kit also and they will have the upgrade ECU tune, here is one for the ISF,

I did an ECU tune and didnt pay anywhere near that price, the price is way to low and I honestly wouldnt risk something that could brick your ECU which would not be covered under warranty. The Lexus ECU is the hardest to crack and I think only a couple companies have been able to do it and there prices range from $800 to $2,000 for the most expensive one.

 

Mike would just do intake and exhaust. If you want better handling get a tanabe strut bar - if you got a '15 or newer GS pick up the takeda cai

 

Did the following to my GS350 FSport 2013 and it drives like a totally different car. In a good way.

- Tanable Strut bar
- Apexi Speed Controller
- K&N Intake
