Thanks to ModInJapan, I finally got my Toms Powerbox and installed it today. Couldn't really test out out to it full limit due to NYC traffic. But here is the quick review....

install was pretty easy and straight forward. Didn't have to take any of the engine compartment panels off to install. Only the 2 boost sensor u have to disconnect and loop into the Powerbox.

As soon as I pulled out of my work garage, I felt the car pull a little harder. When i floored it on the side streets, I definitely feel the harder pull throughout the powerband. When I entered the highway... that's when the traffic started the whole way home and the fun stopped. Lol.

One thing i did find strange is that before the Powerbox install, the boost gauge will show max boost at 15psi at WOT and turn yellow..... after the install, the boost gauge never reach max when I WOT it and always bounce around between 7.5psi and 13psi. Is this normal?

 

Here is the video of my boost gauge not reading correctly....





everything look right?

 

It looks good to me. I suspect you'll see slightly higher boost readings on the low end. Try doing a full 0-80 pull to see where your boost peaks also brake boost and launch the car at 2k rpm. You'll see better 0-60 times

 

It's still reading around 8psi on a WOT pull.


Here is a video before my install of the powerbox at WOT. It reach max boost real quick.

 

Well if it's faking the boost reading to the ECU to make it think it needs to make more boost, kinda makes sense it would read lower on the cluster...put a vacuum/pressure gauge (aka boost gauge) in and see what it actually is.

 

it makes sense. Just didn't know If it was normal to be reading so low after the install

 

Maybe post in the 3IS or RC forums.. seems like several people have installed the Tom's box too.

 

good idea. Thanks

 

Great feedback.

Now that it's more lively to drive it, is there a drop in mpg?
Not a huge concern for me, just curious.

 

only droved it for a day. Droved the car normal to work today and the reading was at 24.3mpg.

 

Very nice.
