i have a gs 300 i am thinking of switching to the 400 or 430 but in the mean time i was wondering if it would be worth the money for performance to get a ecu what does it do on the 300 and have anyy of you with a 300 bought it and had big increase and whats the best and most bang for the buck

 

umm.... what ecu you referring to? there is no ecu out there to boost the performance of the car. the steering wheel ecu only helps to tighten up the steering feel

 

SRT makes one that comes with their Intake, It has a performance gain....but I not sure how much gain on the GS300. Just do a SEARCH for it!

 

... if we can get enough demand for the AEM EMS for the IS300 and GS300/400/430

....ahhh

 

That's what I'm talkin about!!!!
