Is it work on US IS350 model, and is that worth to upgrade. Because it show can be increase about 50hp.

 

Me not sure, think but ECU good not for IS.

 

Last I checked Tom's ecu upgrade can only be performed on Jdm ecus. The only Toyota tied company that can successfully tune the usdm engine ECM is SARD Racing. Within the next few weeks there should be a handful of US forum members with SARD tuned ecms on their ISF. Unfortunately, it appears SARD is not interested in working with IS350 owners at this time :/

 

^Yep, I read the thread with the very same info. SAD.

 

hopefully in time they will.....

 

They've made it pretty clear they will not, and judging by the overall response from the ISF guys over the price to tune their cars, I imagine SARD is regretting putting their time and effort into it. If I had an F, I would jump on that tune for sure. It costs less than I spent to boost my car.

 

yeah makes sense to me completely but makes no sense at all. all the dead end tune threads in the isf section and the company that can do it makes it possibe then they complain about the price smh lol.. Sard has been making things happen toyota wise for a long time so i dont know anyone would think it would be cheap

im sure they see its not going to be a hit in the high performance line of lexus so i doubt the lower models like the 250/350 will see it at all

 

Lmaoooooo

Back on topic: wish I could tune my 350

 

i wish we can tune our cars so we can add hella **** like cams, intake manifold, turbo or supercharger that can go up to 30 psi LOL like honda stuff. haha

imagine a 600hp is350 lol

 

I wonder if they would touch a IS350 with a ISF engine and transmission swap.

 

Yeah, I was signed up...

 

^Was.
