im planning to go EIP Racing tomorrow if they have time for me on the dyno

The IS350 is modded with exhaust and intake
The MS3 is pretty much stock. He has the OEM hi-power exhaust upgrade.

 

Osiris is the tuning software that they use. When you get a dyno tune they put your car on a dyno and adjust the air/fuel ration, timing, etc to optimize the performance of your individual set up.

The best option is to look on the uprev website and find a protuner near you

 

just got back from EIP Racing in Milpitas!
My AFR was really messed up and they improved it by far haha.
Car runs smoother and definitely feel a difference in power.
It was dyno'd on a mustang dynamometer and I was told that my total WHP is around 25+ the total that is showing on the computer.

UPDATED FIRST POST with PICS!
