Hello All,

Returning from a long bout with COVID and happy to be here! 60th birthday coming up and I want to tune my 2013 ES350! Anyone know of a company that does that in St.Louis MO.

 

There is very little you can do to effectively tune a naturally aspirated engine. You can probably get ~10% more power by flashing ECU, switching to high octane gas, getting a new exhaust a K&N filter. But there is not much point in tuning FWD luxo-barge in the first place. It can barely handle 270HP as is. If you want more performance - sell the ES and buy a different car.

But if you still insist on doing something - get a K&N air filter and slap a fuel atomizer on a fuel line.
