That's not how tuning works. You don't just shop online for a tune and which it in arbitrarily with whatever parts you decided to slap on. You can remote datalog and come up with a mediocre tune, but if you can't find a local tuner then you've got the wrong project.
Im not sure I know any tuners who actually have a tune for the is350

Like Cali2is said, RRRacing has everything you'll need. Use a quick search function on the forum and you would've found this without having to make a thread. Their base tune gives you quite a bit of HP for a base tune. You can go to a dyno shop and have them datalog the car, which you can have sent to RRRacing after you purchase their tune and they will provide you with another file with better performance, however they don't do it for free, if im not mistaken.
i heard a lot about rr racing's tune for is350. makes me want to get it but damn $500. maybe one day
If you decide make sure you have all the latest Recalls done to your car. I used another tuner at the time OVT. Since they didn't have my calibration ID on file. I was using my hand held tunner as paper weight for months. The only way to get it updated was to send in my ECU to them. Didn't want to go that route at the time and just sold the tuner.
As of now I still need to get the current air bag, and fuel pressure sensor fixed. Then maybe I'll go ahead and get the RR tune.

Thanks for advice! my car doesnt have any recalls pending. so i assume the pervious owner did them.

IHow do you know your IS350 has the latest Lexus ECU calibration file?
I am based in Sydney Australia and contacted RR Racing and they are unsure about Australia.
I am expecting delivery of my RR Racing Tune for my IS350 RWD F Sport.
Reading the instructions, RR Racing recommend a dyno run post the install of the tune, how crucial is this to do? What things are we looking for, and can this be monitor my a road test with a OBD reader ?
Also during the tune install is it a must to use a battery pack to be connected, how long does it usual take to install the tune?

RedSpencer ? Do u know
No need for a dyno run after the install as it only applies for those that require custom tunes like forced induction. The ECU Tune file will adjust accordingly for bolt-on mods.
It will take approximately 10 minutes for the new file to transfer over to the ECU via the OBD unit. The instructions will recommend that you shut off all potential battery drainers while you upload the RR Racing ECU file (i.e. turn off headlights, radio, nav screen, etc) to minimize any potential issues.
Once the file is installed, it will take approximately 40-50 miles of driving for your Knock Correction Learn Value (KCLV) to return back to its original setting in order to optimize ignition timing advance.
If you have an app like OBD Fusion or Torque Pro, you can play around with your datalogs to see the changes made to the ignition timing advance, AFR, MAF g/s, etc.
Since you don't have the tune installed just yet, now would be a good time to do some pre-tune datalogs so you can see what changes were made after the tune. In my case, I noticed changes made to ignition timing advance and the MAF g/s readings as the higher RPM limit allows for more airflow.

Thanks Reds very useful information, I appreciate your advise..
With the tune files, would your suggest loading the 7,200 Rev limter? From what I have read around more pro's than cons on the higher limit, it is safe as the 2GR-FE in Lotus rev higher than 7,200 and have the same internals?
